Alex Ross, a thirty-year-old psychologist, enjoys the benefits of a close-knit family: her mother and aunt are twins married to two close friends, and Alex and her cousins, Rolf and Stephen, grew up as if they were siblings. When Rolf is killed in a car accident, Alex’s entire family spins into grief and chaos.

Nathaniel, a mysterious art museum curator, soon enters their lives and seems to offer the family solace. Frannie, Rolf’s mother, becomes infatuated with the young man; Alex, who split with her long-term girlfriend in the aftermath of Rolf’s death, finds herself deeply attracted to him. Only Stephen mistrusts Nathaniel—but he soon becomes consumed with the nationwide financial crisis threatening the family’s stability. Will Alex choose Nathaniel over her loyalty to Stephen? Torn between competing desires, fueled by her lifelong but unexamined love of Rolf, she must turn her own training as a psychologist on herself in order to find peace amid the turmoil.
