New York Times best seller John Lescroart delivers a dark, intimate thriller about the price we put on family and the terrible costs of seeking the truth.

Raised by loving adoptive parents, San Francisco private investigator Wyatt Hunt never had an interest in finding his birth family - until he gets a chilling text message from an unknown number: "How did ur mother die?"

The answer is murder, and urged on by curiosity and the mysterious texter, Hunt takes on a case he never knew existed, one that has lain unsolved for decades. His family’s dark past unfurls in dead ends. Child Protective Services, who suspected but never could prove that Hunt was being neglected, is uninformed; his birth father, twice tried but never convicted of the murder, is in hiding; Evie, his mother’s drug-addicted religious fanatic of a friend, is untraceable. And who is the texter, and how is this person connected to Hunt? 

Yet in the present, time is running out. The texter, who insists the killer is out there, refuses to be identified. The cat-and-mouse game leads Hunt across the country and eventually to places far more exotic - and far more dangerous. As the chase escalates, so does the threat, for the killer has a secret that can only be trusted to the grave. Thriller master John Lescroart weaves a shocking, suspenseful tale about the skeletons inside family closets... and the mortal danger outside the front door.
