Follow the rules. That’s what Con Becker does, even when it means denying his own needs. Because one thing he’s learned is that breaking the rules gets you into trouble. It alienates you from your family. It brings you face-to-fangs with death. So Con sticks to his lab in the basement of the Bureau, examining evidence, updating his spreadsheets, and enduring the pain of his damaged body. Until Chief Townsend sends Con on a field mission with Agent Isaac Molina. The task seems simple—recruit allies from among the coyote shifter community—but nothing is easy when your alluring partner has no patience for protocols and regulations. And when monsters attack from the darkness. When obligation collides with desire, Con must decide how to fulfill his mission, keep himself and Isaac alive… and cope with the demons that seek to consume him. And in order to succeed, he just might have to break some rules.
