White Heat

Nate Ferrentino and Rachel Jessop, operatives for the private security company Department 6, are going undercover to expose a new and dangerous cult.
This group has taken up residence in the Arizona desert, in a ghost town called Paradise. Members worship at the feet and in the bed of its charismatic leader, Ethan Wycliff. On his orders, they tried to stone a woman to death, and have been implicated in the disappearance of a teenage girl.

To expose the cult, with its arcane rituals and debauched practices, Nate and Rachel must pretend to be married. But being Nate's 'wife' is the last thing Rachel wants. She and Nate have a history that she'd rather forget. But they have no choice. Wycliff must be stopped.
