Devil in the Details by Lynn Hagen

Abel’s life has turned upside down when he discovers he has a stalker. The person leaves flowers at his door, notes on his car, and he even snapped a picture of Abel and slid it under his door. When a stranger approaches him at work and offers his help, Abel is wary, but accepts. He just didn’t know what he was getting into when he made a deal with a demon.

When Caine accidently touches a chameleon shifter, his worst nightmare comes to life. Bowen transforms into an exact replica of Caine, and vows to destroy Caine’s life. While tracking Bowen down, Caine ends up in Maple Grove and runs into a feisty little human. Demons don’t know who their mate is until they sleep with them, and Abel is on his menu. But can he keep his mate safe while the fake Caine racks up enemies who are determined to track the real Caine down and get their revenge?
