The heart-pounding new thriller from the co-author of five No. 1 James Patterson bestsellers including Judge and Jury and Lifeguard, and the Sunday Times bestsellers The Blue Zone and Reckless.

Leading a tour down the rapids outside Aspen, Colorado, whitewater guide Dani Haller comes across the body of a close friend. Refusing to believe it was an accident, Dani uncovers evidence that backs up her suspicions and takes her case to Wade Dunn, local police chief and her ex-stepfather.

Wade insists the case is closed but Rooster, a hot-air balloon operator, claims he saw something that Dani needs to know. Before she can find out, however, Rooster plunges to his death in a fiery crash. Dani threatens to go public with her evidence, and finds herself thrown in jail.

When ex-detective Ty Hauck receives word that his god-daughter is in trouble, he immediately jumps to her aid. Together he and Dani step foot into a sinister scheme running deep beneath the surface of a quiet, Colorado town that has made a deal with devil to survive.
