Hard-working, divorced mom Hannah is settling into a new neighborhood with her eleven-year-old son, Miles, right next door to her sister Hillary’s sprawling family home. Hannah’s looking forward to a fresh start—for herself and for Miles. But when a six-year-old girl goes missing, the picturesque enclave becomes a hive of search parties, cadaver dogs, and gossip. And when a pair of homicide detectives find evidence that points to someone in the neighborhood, the upscale community turns on Hannah and Miles. In an effort to clear her son, Hannah embarks on her own haphazard investigation. When at last she uncovers chilling—and overlooked—evidence against her brother-in-law, the novel pits sister against sister, neighbor against neighbor, detective against detective, and mother against daughter.
