Atlas becomes homeless and moves into the abandoned Burleson house

Atlas Corrigan's homelessness begins when he is eighteen years old, a few months after his birthday, following a big fight with his stepfather, a man who never really liked him and who kicked him out of the house. With no real father in his life—a man who never had anything to do with him—and a mother who refused to let him move back in because it would upset her new husband, Atlas finds himself with nowhere to go. He had been staying with a friend and his family, but when the friend's father got a job transfer to Colorado, they moved away and could not take him with them. Knowing their kindness was temporary, he told them he was moving back home, but when he actually went back and asked his mother if he could live there until he graduated, she said no. Left with no options, he wandered around for a few days until he discovered the abandoned Burleson house, a condemned property that had been empty since its owner, Mrs. Burleson, died about two years earlier. He decided to stay there until something better came along or until he graduated, since he was already signed up to join the Marines come May, which was still six months away.

Discovery and Secret Observation

Lily Bloom first notices Atlas when she sees a light coming from the old house one night while she is in bed shuffling cards, a habit she uses to calm herself when her parents fight. The light looked more like candlelight than anything electric, so she went to the back porch, found her father's binoculars, and tried to see what was happening, but it was too dark to make anything out. The next morning, while getting ready for school, she saw someone sneaking out the back door of the house—a guy with a backpack who looked around to make sure no one saw him before walking between her house and the neighbor's and going to stand at the bus stop. She had never seen him before, and it was the first time he rode her bus. He sat in the back while she sat in the middle, so they did not talk, but she saw him walk into the school, confirming he must go there. When he got off the bus at the same stop as her that afternoon, she ran straight to her room and watched out the window, and sure enough, a few minutes later she saw him sneaking back inside the empty house. She had no idea why he was sleeping there, since there was probably no electricity or running water, and she briefly wondered if it was a dare, but the pattern of his coming and going convinced her it was real.

Learning His Story

Lily eventually learns Atlas's name from a girl named Katie, who sat next to her on the bus and rolled her eyes when asked, saying only that he was a senior and that he smelled, scrunching up her nose as if it grossed her out. Lily wanted to yell at her and tell her he could not help it, that he did not have any running water, but instead she just looked back at him, and she might have stared a little too much because he caught her looking. One night, after sneaking him in through the back door and into her room, she made a pallet for him on the floor next to her bed, locked the door, and set the alarm for six in the morning so he could leave before her parents woke up. As they whispered in the lamplight, she asked him how he ended up there, and he grew quiet, staring up at her with his hands behind his head before explaining that he did not know his real dad, that it had always just been him and his mom, but she got remarried about five years ago to a guy who never really liked him much. They fought a lot, and when he turned eighteen a few months ago, they got in a big fight and his stepfather kicked him out. He took a deep breath, as if he did not want to tell her any more, but then he continued, describing how he had been staying with a friend until the family moved to Colorado, how he had lied and said he was moving back home, and how his mother would not let him. He turned his head and looked at the wall as he admitted he just wandered around for a few days until he saw that house, figuring he would stay there until something better came along or until he graduated, since he was signed up to go to the Marines come May. Lily notes in her diary that May is six months away, and the weight of that waiting period hangs over their secret arrangement.

The Town's Prejudice and Lily's Awakening

The town's reaction to Atlas's homelessness reveals deep-seated prejudice. When word eventually gets out that Atlas had been staying in the old house and that he had been homeless, Lily's father is not arrested for what he did to Atlas, and instead becomes revered for his heroic act—saving his little girl from the homeless boy who manipulated her into having sex with him. Katie, the same girl who had wrinkled her nose at Atlas's smell, tells people on the bus that she tried to warn Lily about him, claiming she knew he was bad news from the moment she laid eyes on him. Lily, furious, turns around and tells Katie she can go to hell, insisting Atlas was a better human than she would ever be, and that if she ever heard one more bad thing about him, she would regret it. Katie just rolls her eyes and asks if Atlas brainwashed her, calling him a dirty, thieving homeless kid who was probably on drugs and who used her for food and sex. This moment crystallizes the novel's critique of how society others the homeless, reducing a person's entire character to their circumstances.

Lily's experience with Atlas fundamentally changes her worldview. She writes in her diary that she will never be able to respect rich people now, knowing they willingly choose to spend their money on materialistic things rather than using it to help other people, though she makes an exception for Ellen, the talk show host she addresses her diary entries to, because of all the charities she supports. She reflects on her own father, who once refused to give money to a Salvation Army bell ringer outside a grocery store, lecturing her about how people take advantage of the government and how it is not his fault that other people do not want to work. Lily admits she believed him for three years, thinking homeless people were homeless because they were lazy or drug addicts or just did not want to work, but now she knows that is not true. She realizes her father was using the worst-case scenarios to excuse his own selfishness and greed, and she swears that when she grows up, she is going to do everything she can to help other people, just like Ellen, though probably not as rich. This awakening, born directly from Atlas's homelessness, becomes a defining moral thread in her character.

Consequences and Lasting Significance

The event of Atlas becoming homeless and moving into the Burleson house has far-reaching consequences that echo through the entire novel. It is the origin of Lily and Atlas's secret friendship, their first kiss, and the deep bond that persists across years and distance. It is also the cause of the violent confrontation when Lily's father discovers Atlas and beats him up, an act that the town reframes as heroism and that leaves Lily with her first and only panic attack, so severe that an ambulance had to be called for her as well. The shame and gossip that follow—Lily's father saying she shamed their whole family—shape her adolescence and her determination to break the cycle of abuse she witnesses at home. Years later, when Lily is an adult and needs to escape Ryle's violence, it is Atlas she runs to, the same boy she once hid in her room, now a man with an alarm system and a home of his own. She reflects that being there fills her with guilt and shame, as though calling Atlas lends credibility to Ryle's anger, but she also acknowledges she feels safer there than anywhere else she could possibly go. The trajectory from the abandoned Burleson house to that moment of refuge completes a circle, showing how an act of childhood compassion, born from witnessing homelessness, becomes the foundation of adult salvation. The novel ultimately uses Atlas's story to argue against the dehumanizing narratives society builds around the homeless, insisting instead on the dignity and humanity of a boy who simply had nowhere else to go.
