Marco Carrera and Irene Carrera's sibling relationship

Marco Carrera and Irene Carrera’s sibling relationship is defined by an intimacy that others in the family repeatedly fail to recognize. Marco admires Irene, understands the danger beneath her volatility, and intervenes when he believes she may take her life at the Mulinelli. His attention cannot prevent her eventual suicide, but it makes him both her witness and the family member who carries her memory forward.

Unequal Closeness

Marco regards Irene as his “polar star,” a model of youth and a person whose intelligence and torment make her seem exceptional. Her anger, anxiety, and rebelliousness distinguish her in his eyes; where relatives have grown accustomed to her crises, he continues to understand, excuse, and love her. That loyalty persists despite what the narrative describes as her many acts of unkindness. The relationship is not easy or reciprocal in any simple sense: Irene does not want Marco beside her, or seem to want anyone in the family close, while Marco remains oriented toward her and alert to what she may do.

The family’s familiarity with Irene’s changing moods has dulled its response. Her scenes, silences, apparent recoveries, and renewed outbursts have become recurring features of family life, and the adults’ alarm has receded. Marco’s regard sets him apart from this habituation. His attention is not merely affection: he notices when a familiar pattern has become an immediate threat, even when the rest of the household does not.

The Mulinelli Crisis

In August, while the family is staying in Bolgheri, Irene’s plans for the summer have fallen apart. A friend’s withdrawal has upset her hopes of travel and exposed, once again, the fragility of her social connections. Her therapist is away for the month, and the long, unfamiliar international number left for emergencies is difficult to use. At home, the family is also preoccupied with Marco’s growth treatment, a concern discussed in the evenings while Irene listens without their knowledge. These circumstances form the background to the crisis, but the account does not reduce her danger to any one of them.

One evening, after a sparse dinner, Irene says she is going to secure the family’s Vaurien sailboat before the storm. Her explanation sounds ordinary, but Marco immediately understands that she is heading toward the Mulinelli, a dangerous stretch of water by the family’s beach. Four people had drowned there, deaths the family understood as suicides. Their mother is washing dishes and Giacomo is drying them; neither tries to stop Irene. Marco decides that it is his responsibility to follow. Though he is much smaller than Irene, he leaves the house alone and pursues her toward the dunes.

Irene repeatedly orders him to go home. She knocks him down and continues toward the shore, while Marco follows, prepared to stop her if necessary. The confrontation takes place without other people nearby to help. At the beach, with the whirlpools visible ahead, Marco stays ready to intervene. Irene instead turns to the boat, secures a rope around it, and hauls it away from the water toward the shed. Marco watches without helping, still prepared to act but uncertain what to do. Once the boat is safe, Irene unties the rope from her waist and secures it to the shed. The immediate danger passes without a direct conversation about what Marco believed she intended.

Care Without an Explanation

The scene ends in a gesture of mutual proximity rather than an explicit reconciliation. Irene and Marco walk home trying to match their pace. Their positions reverse ordinary expectations: Marco puts an arm around his sister’s waist, and Irene rests hers across his shoulder. She occasionally touches him lightly at the back of the neck. The story gives this small, shared walk weight precisely because the crisis has not been explained between them. Marco has followed her, and Irene has allowed him to remain beside her; their unspoken understanding is expressed through movement and contact instead of a confession or promise.

That night also exposes the limits of the family’s awareness. Marco’s perception brings him to the shore, but it does not give him certainty about what Irene will do, nor does the episode establish that he can protect her permanently. The relationship therefore holds both a real act of care and an unresolved fear: his vigilance is meaningful, but it cannot make him master of her distress.

A Relationship Reframed by Loss

The book later places this intervention beside Irene’s eventual death. In an earlier episode, Marco sees her lying unconscious after an accident and fears she is dead; she has only fainted. The narrative then links the desperation he feels during that brief uncertainty to the look he will later turn on her corpse in the morgue of the Cecina hospital, seven years afterward. It also recalls a childhood wish, made after a shooting star at Bolgheri, that Irene would not die by suicide. The sequence frames his fear as long-standing, not as a reaction invented after her death.

The final account of the Mulinelli is devastatingly plain: Irene’s body is returned by the water to the shoreline. For Marco, the earlier night when he followed her to the beach becomes one of many occasions on which she might have died but did not; her eventual death gives that rescue attempt a painful retrospective significance without making it a successful prevention of the loss. Years later, when he is old, nearly alone, and facing his own death, he marks a phrase about darkness and confusion while thinking of Irene. His memory preserves her not only as the source of family pain but as the sister he continued to understand and love.

The Family’s Unspoken Wound

Irene’s death also becomes part of the unresolved rift between Marco and Giacomo. During their parents’ illness, the brothers repeatedly find themselves near opportunities to forgive one another, including in the dim hospital corridor, but neither manages to begin the conversation. Looking at their parents’ decline, Marco recognizes that the family’s knot reaches beyond their old disagreement and is bound up with the damage left by Irene’s death. The siblings’ loss thus remains active in the next generation of family relationships: it is not only a past tragedy but part of what keeps reconciliation difficult.

The relationship’s central contrast is between Marco’s attentive loyalty and the family’s repeated failure to perceive how exhausted Irene has become. That contrast should not be mistaken for a claim that Marco could have controlled the outcome. The book presents his care as concrete and consequential in the moment at the Mulinelli, while showing that love, vigilance, and shared history cannot guarantee rescue. Irene remains more than a crisis in his story: she is the sister whose presence shaped his sense of responsibility and whose absence continues to inhabit his memory.
