The New York Times Bestselling master of suspense is back with a riveting thriller, as reward seeker Colter Shaw plunges into the woods and races the clock in a case where nothing is quite what it seems. The Times Book of the Month (November 2022) THERE ARE TWO FUNDAMENTAL RULES OF SURVIVAL. #1: NEVER BE WITHOUT A MEANS OF ESCAPE. Allison Parker is on the run with her teenage daughter, Hannah, and Colter Shaw has been hired by her eccentric boss, entrepreneur Marty Harmon, to find and protect her. Though he’s an expert at tracking missing persons―even those who don’t wish to be found―Shaw has met his match in Allison, who brings all her skills as a brilliant engineer designing revolutionary technology to the game of evading detection.
