From the bestselling author of A Darkness More than Night comes a searing thriller about a simple wrong number that opens a line into terror. Henry Price has a whole new life-new apartment, new telephone, new telephone number. He soon discovers that the messages on his line are for a woman named Lilly, and she is in serious trouble that could cost him all he holds dear. Pierce is inexorably drawn into Lilly's world, and it's unlike any world he's ever known. It is a nighttime world of escort services, websites, sex, and secret identities. Pierce tumbles through a hole, abandoning his orderly life in a frantic race to save the life of a woman he has never met. Pierce's skills as a computer entrepreneur allow him to trace Lilly's last days with some precision. But every step into Lilly's past takes Price deeper into a web of inescapable intricacy-and a decision that could cost him everything he owns and holds dear.
