The Trench

Publication and place in the series

The Trench is a science-fiction thriller by American novelist Steve Alten, published by Kensington in 1999. It is the second novel in Alten’s Meg series, following Meg, and carries forward the premise that the prehistoric giant shark known as the megalodon has survived into the modern age. The book combines deep-sea adventure, creature horror, and fast-moving commercial suspense. Marine science and ocean exploration give the story a recognizable framework, while the enormous predator turns the unknown into an immediate physical danger. Rather than restarting the story, Alten builds on the characters and consequences established in the first novel.

Story

The story takes place years after Jonas Taylor captured a young megalodon named Angel and confronted her mother. Angel has since grown, but remains in a huge marine tank. She wants to escape, making the effort to contain her an increasingly dangerous problem. At the same time, Terry travels into the depths of the Mariana Trench to investigate what happened to a crushed submersible. These parallel threads place the characters at two different limits of human control: a powerful animal confined in an artificial enclosure, and a remote ocean environment that people can scarcely explore. As the danger intensifies, Jonas must face the giant predator again. He uses himself as bait, entering a lethal struggle between human beings and a creature suited to the darkest reaches of the sea. The investigation, the threat of escape, and the final confrontation together make the ocean both the setting and the source of the novel’s central suspense.

Themes and approach

The book’s central concern is the unequal relationship between people and the natural world. Knowledge, machinery, and courage may help the characters act, but they cannot make the deep ocean fully predictable or render a giant wild animal harmless. Angel’s captivity gives this conflict a human-made dimension: the attempt to possess and control a formidable creature may create new dangers instead of resolving them. The Mariana Trench, meanwhile, represents the limits of what can be seen and understood. It is a real geographical setting, but also a narrative frontier where incomplete information makes every descent consequential.

Alten’s approach is that of the popular science-fiction thriller. He draws on the recognizable idea of an ancient shark and places it in a contemporary adventure, using action and escalating peril to carry the reader through the plot. The sequel’s particular interest lies in what happens after the first encounter: the captured young shark has matured, containment is under pressure, and another mystery draws characters down into the sea. Suspense comes not only from the creature itself, but from decisions made in environments where people have little room for error.

Background and legacy

The Trench followed the commercial breakthrough of Meg. Alten began writing the earlier novel in 1995, while facing financial pressure and raising five children, and worked on it at night and on weekends. After the first book secured a publishing deal, Kensington published this sequel, which also reached bestseller lists. That background helps explain the book’s clear commitment to accessible, high-concept storytelling: scientific and prehistoric ideas serve an energetic adventure rather than a scientific treatise.

The novel remains significant as an early continuation of the Meg series, extending its distinctive premise and carrying forward Jonas Taylor and Angel into a new crisis. It helped establish the series as a durable strand of creature-centered ocean suspense and remains one of Alten’s best-known works. The later film The Meg was based on the first novel, not directly on The Trench, but the film’s popular visibility renewed attention to the series and its central image of a prehistoric shark in the modern sea. For readers of marine thrillers, The Trench is both a sequel to a major commercial success and a self-contained tale of exploration, confinement, and survival.

About the Author

Steve Alten

Background and education

Steve Alten, born Steven Robert Alten on August 21, 1959, in Philadelphia, Pennsylvania, is an American science-fiction and thriller writer. He grew up in Philadelphia and pursued an unusual path for a novelist: he earned a bachelor’s degree in physical education from Pennsylvania State University, a master’s degree in sports medicine from the University of Delaware, and a doctorate in sports administration from Temple University. His formal training was not in literary studies, but his work often begins with scientific, medical, athletic, or prehistoric ideas and turns them into accessible popular fiction.

Early career

Alten’s entry into publishing followed a difficult period. He was financially strained and raising five children when he began turning a long-standing story idea into a novel. In the summer of 1995, he started writing Meg on an old word processor. Because he still had daytime work, he wrote late at night, often from about ten o’clock until three in the morning, and continued on weekends. He completed the manuscript after roughly eight months of work. He then lost his job; four days later, his literary agent, Ken Atchity, arranged a competitive auction involving six major publishers. Bantam won a two-book deal. The story of Meg’s creation and sale became an important part of Alten’s early public profile, illustrating how a sustained personal project developed into a commercial breakthrough.

Published in 1997, Meg reached bestseller lists including those of The New York Times, The Wall Street Journal, and USA Today, and its rights were sold internationally. Alten has described his aim as entertaining readers who want an action-packed escape, rather than writing primarily to satisfy literary critics. That outlook is reflected in his fiction: strong premises, urgent plots, recognizable scientific or historical material, and a clear emphasis on suspense. Early success did not mean a smooth career. Accounts of his publishing history describe setbacks involving a later manuscript and film rights; Alten responded by continuing to improve his storytelling and eventually re-established his career.

Major works and reputation

Alten is best known for the Meg series, which imagines the survival of the prehistoric megalodon in the modern ocean. Meg (1997) introduced the premise and its central character, Jonas Taylor. The Trench (1999), the second book, continued the story with Jonas, the young shark Angel, and a new crisis in the Mariana Trench. Later series entries include Meg: Primal Waters (2004), Meg: Hell’s Aquarium (2009), Meg: Nightstalkers (2016), and Meg: Generations (2018). His other novels include Domain (2001), Goliath (2002), Resurrection (2003), and The Loch (2005). Across these books, he has explored disaster, technology, ancient life, and dangerous creatures through the fast-moving conventions of the commercial thriller.

Meg later became the basis for the 2018 film The Meg; that adaptation drew on the first novel rather than directly adapting The Trench. The film broadened the visibility of Alten’s central creature premise, while the continuing series established his reputation among readers of creature features and marine adventure. His lasting contribution is chiefly to popular genre fiction: he made the megalodon a sustained modern thriller protagonist and combined speculative science, deep-sea settings, and cinematic action in a recognizable series format. Alten is alive as of the available biographical information, and the Meg books remain the defining part of his public reputation.

Storylines

Event 1

Proteus abyss disaster

The [Proteus abyss disaster](entity:event-recall-event-proteus-e27a486c597c) is the catastrophic loss of a submersible in the [Mariana Trench](entity:location-recall-location-mariana-trench-6c313f16b35a), where three unidentified objects approach during seabed work and the [Proteus](entity:object-recall-object-proteus-937f67ff0352) is struck, suffers damage to its hull, and implodes. Four people die. The sequence makes the disaster a collision between a vulnerable vehicle and an overwhelming external threat, while its aftermath leaves the cause unresolved: a reported hull breach is later recast by Celeste as probable pilot error. ## Seabed Work and the Warning The Proteus is operating on the trench floor while its robotic arms work near a cluster of tubeworms. The arms stir clouds of mud as the crew continues its task. The danger first registers not as a visible attacker but as a change on the instruments: loud sonar warnings draw the pilot’s attention to a printout and screen, where a tight cluster of large objects has appeared. The others are still working and do not initially look up, making the warning a sudden break in the routine of the operation. The sonar report gives the approach a precise, alarming shape. Three objects are bearing two-one-five, 7.4 kilometers away, moving at fifteen knots and closing directly on the Proteus. The crew attempts to contact the surface but receives no response. With no reply from above, the people aboard understand that they must face the approaching threat without immediate outside assistance. The report establishes the objects’ number, direction, distance, and speed, but does not identify them; the crew knows that something is coming before it knows what it is. ## Impacts and Loss of Hull Integrity As the objects draw near, the captain whispers that they have arrived. For a long moment, the only sound is the Proteus’s propeller. Then a sudden jolt pitches the submersible to starboard and throws Barry against his console. The pilot struggles with the navigational controls and reports that the Proteus is not responding properly. When Ellis asks what it hit, Barry says that the Proteus has been hit rather than having collided with something under its own control. The distinction shifts the scene from a possible navigation error toward an assault from outside. The crew tries to shake the attacker. The pilot swings the submersible hard to port and then back to starboard, but the maneuver does not restore control. Linda warns that a plate is loosening. Grinding metal follows along the hull; the pilot touches a titanium rivet in the plate overhead, finds moisture, and recognizes it as seawater. He hopes to see the [Benthos](entity:object-recall-object-benthos-91c8749f0ebf) through the viewport, but the breach is already tangible inside the cabin. The captain reports that the tail fin is being torn loose, adding damage to the vehicle’s ability to maneuver to the warnings about the hull itself. A further warning confirms that the plates are losing integrity. [Arie Levy](entity:character-recall-character-arie-levy-2370520a8d4c) begins to call attention to a third creature, but a tremendous blow to the bow interrupts him, throwing Linda and Ellis to the floor and pitching Barry over the navigation console. The sequence has escalated from sonar contacts to repeated attacks on different parts of the submersible: its handling is compromised, a plate is loosening, seawater is present, the tail fin is threatened, and the bow is struck. The crew receives no demonstrated opportunity to stabilize the craft before the next impact. ## The Crew’s Last Moments and the Reported Outcome The bow strike leaves the danger close enough to be seen: a luminous crimson eye peers through the viewport. Arie presses his palm against the reverberating titanium plate and thinks of the information he has struggled to acquire but has not been able to report. He also thinks of his wife and children, whom he has forsaken in the line of duty. His thoughts place the mission’s unfinished work beside the personal cost of remaining aboard; the account does not say that he succeeds in sending the information or in escaping. The disaster’s outcome is reported afterward. Jonas hears from [Benedict Singer](entity:character-recall-character-benedict-singer-da16cd9f285c) that the Proteus imploded in the Trench and that four people died. The message gives the loss its definitive scale without identifying the dead in that conversation. The earlier scenes have shown damage accumulating aboard the submersible; the report compresses that crisis into its final consequence, the implosion and the deaths. For Jonas, the news is immediately devastating, and [Benedict](entity:character-recall-character-benedict-e0d31a798805)’s next request is for him to meet about the [Goliath](entity:object-recall-object-goliath-b02fa09e2de0). ## Competing Explanations and Narrative Significance In a later conversation with [Masao](entity:character-recall-character-masao-e775be666065), Benedict describes the [Proteus disaster](entity:action-recall-action-proteus-disaster-dbb755589bf1) as a tragedy in which four valued personnel and friends were lost, including the project manager. He says the last word received was the pilot’s report of a hull breach. That account is consistent with the crew’s earlier report of seawater and failing plates, but it does not disclose what caused the breach. Celeste, Benedict adds, believes pilot error is more likely than a malfunction. Her explanation is presented as a belief, not as a confirmed finding; the narrative therefore preserves a gap between the crew’s experience of being struck and the post-disaster attribution of responsibility. That gap matters because the scenes aboard the Proteus give the reader a specific chain of external impacts and worsening structural damage, while the later account offers no investigation or resolution that reconciles those events with Celeste’s suspicion. The disaster is not established as a simple mechanical malfunction, nor is the identity of the attackers settled in the report. Its uncertainty becomes part of its consequence: Jonas receives news of four deaths alongside a demand connected to the Goliath, while Masao hears an account that may redirect attention toward the pilot. Elsewhere, the novel returns to the vulnerability of submersibles under pressure, though those later incidents are distinct from the Proteus disaster. The [Prometheus](entity:object-recall-object-prometheus-c0b532319152) is jolted sideways during work with its sediment-sampling equipment; a [Kronosaurus](entity:creature-recall-creature-kronosaurus-3ed5159cdbf5) strikes the [Epimetheus](entity:object-recall-object-epimetheus-1c00ada1d5a2); and the Benthos’s titanium plates buckle before level B implodes under 1,160 atmospheres of pressure. These episodes do not explain what happened to the Proteus. In the broader narrative, however, they place its loss within a recurring world in which deep-sea machinery can be abruptly overwhelmed, and in which a warning, a damaged hull, or an attempted response may arrive too late to prevent catastrophe.

Event 2

Megalodon capture operation

The [Megalodon capture operation](entity:event-recall-event-f27b9b9e3322) was [Jonas Taylor](entity:character-recall-character-jonas-taylor-a8b5584e89b0)’s return to the [Mariana Trench](entity:location-recall-location-mariana-trench-6c313f16b35a), where a mission to retrieve a damaged seismic robot became a fatal encounter with two Megalodons and a turning point in his public life. The operation joined scientific recovery to Jonas’s hope of redemption, but its consequences were divided: a member of the Tanaka family died, Jonas’s career was restored, and his decision to pursue capture rather than simply kill the female remained a source of guilt. ## Causes and Background Years before the operation, Jonas had encountered a [Megalodon](entity:creature-recall-creature-megalodon-2f0832361ac9) in the trench and fled upward in disregard of protocol. The rapid ascent malfunctioned the submersible’s pressurization system, killing both scientists aboard and ending Jonas’s career as a deep-sea pilot. He spent the next seven years trying to establish that the creature existed, giving up piloting to study paleobiology. Although he developed a theory that Megalodons had migrated to the warmer abyssal waters of the Mariana Trench during the [Last Ice Age](entity:time-recall-time-a479aab55dc9), colleagues dismissed his work and institutions barred his papers. This history made the proposed return more than a technical assignment: it tested whether Jonas could go back to the place associated with both his terror and his professional failure. The opportunity came from [Masao Tanaka](entity:character-recall-character-masao-tanaka-88949621cb5b), Jonas’s old friend and mentor and the founder of the [Tanaka Institute](entity:organization-recall-organization-tanaka-institute-0cfaef7ad481). [Masao](entity:character-recall-character-masao-e775be666065) was developing an artificial lagoon off the Monterey coast as a habitat for whale research, with a joint venture with the Japanese government helping finance the project. Several [UNIS](entity:object-recall-object-unis-b3ed0d946aa7) seismic-detection robots deployed on the Mariana Trench floor had malfunctioned, and Masao needed Jonas to help retrieve one. Jonas initially refused, unable to face the trench. With his first marriage deteriorating and his career in disarray, however, the possibility of redemption became difficult to resist. He later acknowledged that Masao had persuaded him to go, but that he had also wanted to return. [Terry](entity:character-recall-character-terry-bb0dcf794a8d)’s involvement sharpened the decision. Masao’s daughter was prepared to take her brother’s place on the mission if Jonas would not accompany him. Jonas therefore went down in a one-man submersible to escort Masao’s son and recover the damaged robot. His later account did not present this choice as sound judgment: he recognized that ego and emotion had impaired his decision-making, and that entering the abyss alone had been reckless even if the Megalodon had not been there. ## The Encounter in the Trench The danger came not from one animal but from two. The first Megalodon attacked the mission and killed Masao’s son. During the attack, the animal became tangled in the submersible’s cable. The surface ship, unaware of what had happened below, began hauling the cable upward, drawing the entangled creature toward the surface. The recovery operation had thus turned into an unintended ascent of a living predator, with the people at the surface not knowing what the cable was bringing up. A second animal appeared: a larger female. She began feeding on the helpless male and ascended through the cold water. The encounter overturned the premise of a controlled scientific retrieval. The robots and the one-man submersible had taken Jonas back to the trench for a defined task; the animals’ movements instead dictated the crisis, while the ship’s unwitting haul brought the first creature out of the depths. Jonas later identified the female as [Angel](entity:character-recall-character-angel-b4ecd11d5f8e)’s mother, connecting this earlier operation to the animal encountered in the later events of the story. The operation ended with Jonas forced to kill a Megalodon he had wanted to save. In recounting the decision, he singled out his attempt to capture the female rather than kill her as his greatest mistake. The evidence presents both the immediate loss and the ethical conflict: Jonas had spent years arguing that the creature existed, yet the encounter placed him in a position where preserving it and protecting people could no longer be treated as the same objective. His later remorse also reached beyond the mission’s immediate casualties, as he associated his choices with the deaths of other innocent people. ## Consequences and Aftermath The operation transformed Jonas’s standing. Once ridiculed for his research, he was suddenly celebrated as the man who had killed a Megalodon, and his career was vindicated almost overnight. Talk shows, television specials, and reporters followed; the encounter became public spectacle as well as scientific proof. The story’s reversal is stark: the same animal that had made Jonas’s claims seem impossible made him internationally famous when its existence could no longer be denied. The return also reshaped Jonas’s private and working life. He and Terry married, and Masao made Jonas a partner at the Tanaka Institute. A year later, the lagoon in Monterey opened, with a captured female Megalodon pup as its most popular live exhibit. The scientific success and public attraction were inseparable from the danger that had produced them. Eight months after the lagoon opened, Jonas and the Institute became defendants in a $200-million class-action lawsuit brought by relatives of people killed by Megalodons. Terry was four months pregnant when the trial began, and the proceedings drew intense media attention. Thus the operation’s fame did not settle its moral consequences: it helped establish an exhibit and a celebrity, while also making the human cost a public legal and personal burden. ## Narrative Significance The operation is a reversal of Jonas’s first descent. His earlier panic ended his piloting career and left the existence of the Megalodon unproven; this return confirmed his theory and restored his professional reputation, but it did so through another death and a choice he later regretted. The sequence resists a simple triumph narrative: vindication arrives alongside bereavement, and the successful capture enterprise grows from an encounter Jonas himself associates with preventable harm. The event also establishes the tension between scientific discovery and control. The damaged UNIS robot gives the descent a practical purpose, while Jonas’s wish to save the Megalodon invests it with a larger ambition. Yet the cable, the unknowing ship, and the female’s arrival expose how little control the mission has over what it brings upward. The lagoon’s later popularity extends that tension into a public attraction: the animal becomes a spectacle, while the lawsuit recalls the people killed in the same chain of events. In Jonas’s recollection, the defining outcome is therefore not fame alone, but the lasting gap between what he hoped to protect and what his decisions cost.
