The Loverlys’ young son is in a coma after falling from his bedroom window in the middle of the night. His mother, Whitney, will not speak to anyone. Back home, their friends and neighbors are left in shock, each confronting their own role in the events that led up to what happened that terrible night: the Parks, the Loverlys' best friends; the Goldsmiths, who are struggling to start a family of their own; and the Portuguese couple who care for their adult son with a developmental disability and watch their neighbors go about their busy lives. The story spins out over the course of one week, in the alternating voices of the women in each family as they are forced to face the secrets within the walls of their own homes, and the uncomfortable truths that connect them all to one another.

Blythe Connor is determined that she will be the warm, comforting mother to her new baby, Violet, that she herself never had. But in the thick of motherhood’s exhausting early days, Blythe becomes convinced that something is wrong with her daughter --- she doesn’t behave like most children do. Or is it all in Blythe’s head? Her husband, Fox, says she’s imagining things. The more Fox dismisses her fears, the more Blythe begins to question her own sanity, and the more we begin to question what Blythe is telling us about her life as well. Then their son, Sam, is born --- and with him, Blythe has the blissful connection she’d always imagined with her child. Even Violet seems to love her little brother. But when life as they know it is changed in an instant, the devastating fallout forces Blythe to face the truth.
