When Violet DuBay's friend Khloe confides that her dad is a Christian, it's the one secret Violet can't keep. Turning in Khloe's dad to the Constabulary is her duty. Her decision becomes an opportunity to infiltrate the Christian resistance; but as she gets to know Marcus, Lee, and the others, she's compelled to question the things her society has taught her about God and His followers.

Clay Hansen persuades his family to join him at an underground church meeting and brings Violet, his teen daughter Khloe's best friend. That night, the church is raided. He and his wife escape, but in the chaos, he loses Violet and Khloe. How can he find them with the Constabulary monitoring his every move? If the God who once spared Khloe won't intervene, Clay will have to save her himself.
