Though her father lies dying in a hospital north of New York City, Elsa cannot refuse a call for help. A teenage girl has gone missing from Forest Hills, Queens, and during the critical first hours of the case, a series of false leads hides the fact that she did not go willingly. With each passing hour, as the hunt for Ruby deepens into a search for a man who may have been killing for years, the case starts to get underneath Elsa's skin. Everything she has buried - her fraught relationship with her sister and niece, her self-destructive past, her mother's death - threatens to resurface, with devastating consequences. In order to save the missing girl, she may have to lose herself...and return to the darkness she's been hiding from for years.
