New York Times bestselling author Mike Omer returns with chilling twists and turns for a hostage negotiator with a dark past in this explosive second installment of the Abby Mullen Thrillers.

As a child, Abby Mullen escaped the insidious Wilcox cult when it literally went down in flames. Years later, she's the NYPD's best hostage negotiator and a mother. She thought the worst part of her life was behind her. Until now. Armed conspiracy theorists called the Watchers have attacked the local high school-and taken her daughter hostage.

With the delusional Watchers holding her child at gunpoint, the unflappable Abby might be at her breaking point. But the clock is ticking on her daughter's life, and she has no choice but to negotiate with the paranoid group and discover their leader's secret before it's too late.

As Abby peels back the layers of mystery surrounding the Watchers, there's always another puzzle underneath. And it seems to be leading back to the dark past she's spent her whole life trying to forget.
