Murder is an art but the hitman’s method is simple: FIND. TRACK. TARGET. KILL. It’s known as the kill chain – and when her father’s car is found at the bottom of a ravine, Evan Delaney must face the possibility that he has reached the end of the chain. When Evan’s phone rings and she hears the sinister voice on the line, her suspicions are confirmed: Phil Delaney has been kidnapped, and those who hold him want something Evan has only 72 hours to find. Racing against time, Evan follows a trail into the very heart of darkness. A trail that will lead her and her loved ones to their deaths . . . unless Evan can break the kill chain.
