Twelve year-old Callie Rich wouldn’t know what a normal childhood looks like. She and her family have been a part of the Lambs of Zion church their entire lives, existing in a well-guarded pocket of the American southwest where modernity and independence are shunned. When their leader, the Prophet, excommunicates her father—one of his closest advisors—and takes Callie to be his next bride, it has to be a mistake. One town over, private detective Max Barker is well aware of the polygamist cult on the Arizona-Utah border, but he keeps his distance like everyone else until Callie’s father shows up on his doorstep begging for help. His family is in danger and he has the proof that could bring the whole organization—and its leader—crashing to the ground. Max, hoping to make good on a promise he’d kept to a former Lamb, decides to help. Unaware of her father’s plan, Callie joins up with a group of other wives looking to escape, but someone inside the church knows what they’re up to. While Max and Callie’s father work to infiltrate the church for evidence, Callie and the other women of the LoZ must hurry and leave before the Prophet takes drastic action to keep his church, his family, and his legacy intact.
