Short Summary

Amanda Delanoe, a successful Parisian art gallery co-owner, becomes entangled with two very different men: charming publisher Olivier Saint Albin and her abusive ex-boyfriend Tom Quinlan. As she navigates a passionate but complicated affair with Olivier—who is married to a woman hiding her own secret—Tom’s obsessive jealousy escalates into stalking and violence. The story weaves themes of deception, independence, and hidden identities, culminating in a dangerous confrontation that forces everyone to confront the truth. By the end, Amanda and Olivier find a path forward, while several characters embrace new beginnings.

Full Summary

Amanda Delanoe, 39, co-owns Galerie Delanoe in Paris with her friend Pascal Leblanc. She is cautious in love after a painful affair with a married man. At a dinner party, she meets Olivier Saint Albin, a publisher, and they share an instant connection. But Olivier does not call for two months, leaving Amanda disappointed. They reconnect at a Picasso retrospective and begin a romantic relationship.

The relationship deepens, but Amanda discovers Olivier is married to Stephanie Saint Albin, with whom he has two adult sons. He claims they have an "understanding"—a marriage of convenience. Amanda, hurt by the deception, ends the relationship. However, Olivier persists, proposing a one-year trial after which he will divorce if they remain in love. Despite her reservations, Amanda agrees.

Meanwhile, Amanda’s college ex-boyfriend Tom Quinlan resurfaces. He is in Paris on sabbatical writing a thriller. Tom becomes increasingly possessive and threatens Amanda’s new relationship. He lures her to a movie and attempts to rape her; she escapes and reports it but declines to press charges. Soon after, her apartment is vandalized and a stalker leaves a gutted fish at her door. Police suspect an erotomaniac stalker, and Amanda installs security.

Stephanie suffers a severe riding accident, requiring extensive care. Olivier feels obligated to stay with her, while Amanda withdraws, believing he will not leave his wife. Tom’s behavior escalates: he breaks into Amanda’s apartment and attacks her with a knife. Olivier, who has been searching for Amanda, arrives in time to stop the assault and is wounded. Tom is arrested and charged with attempted murder and rape; Interpol reveals he has a history of psychosis.

During her recovery, Stephanie confesses to Olivier that she is a lesbian and has been in a twenty-year relationship with her friend Lizzie. She asks for a divorce to marry Lizzie. Olivier, stunned, admits he wants a divorce to be with Amanda. They agree to separate amicably. A rainbow appears over Paris as a symbol of renewal.

Amanda and Olivier reconcile and plan a life together. Stephanie and Lizzie marry in a ceremony at the Paris Polo Club, with Olivier walking both brides down the aisle. Amanda, now pregnant with Olivier’s child, watches the wedding. The novel ends with a reflection on life’s unpredictability and the importance of finding the right person, regardless of others’ opinions.
