In this powerful follow-up to his action-packed thriller The Kill Clause， Gregg Hurwitz， the new maestro of pulse-pounding suspense， ratchets up the excitement with another sensational page-turner featuring Tim Rackley， a driven lawman motivated by honor， morality， and a deep sense of justice. Called back into the fold of the U.S. Marshals Service， Tim is tasked with retrieving Leah Henning， the daughter of a powerful Hollywood producer， from a mind-control cult. As Tim wends his way deep undercover into an insidious operation called The Program， he confronts a brand of mind-warping manipulation beyond his worst expectations. Tim becomes enmeshed with a diverse band of characters—from the charismatic， messianic leader T. D. Betters to a cult reject burnout to the intelligent yet highly vulnerable Leah herself—and finds himself caught in a shadowy landscape of lies， manipulation， and terror. At stake: innocent minds—maybe even his own.
