His loyalty is boundless. Her magic is relentless. Together, their fates are intertwined. For centuries, Azimuth has been shackled in servitude to the demon prince Belial. But when he's ordered to monitor a fledgling summoner named Meri, he feels a strange protectiveness towards her that defies his daemonic nature. Torn between duty and desire, Azimuth takes dangerous risks to shield Meri as she chases dark power.

A daemon is offering me the name of my parent’s killer, for a price. I’ve spent my life hunting the daemon who killed my parents. I swore long ago to do anything necessary, including summoning the deadly creatures to hunt for clues, even knowing I walked a razor’s edge every time. Any one of them might turn on me and kill me, too. When Azimuth, a sweet-talking daemon with ice-blue eyes and a voice like butter, shows up dangling the knowledge I seek in return for a high-risk job, I feel compelled to accept his offer. Sure, I’m wary of the helpful daemon, but the prize is too tempting to pass up. So what if my pulse races when he touches me or I can’t stop thinking about how his lips will feel on my skin? I’m embarrassed that I can't seem to keep myself from dwelling on forbidden fantasies starring Azimuth. Remembering that all daemons are my enemy and that nothing’s going to get in my way helps me. Nothing, including my forbidden attraction to an enemy. An enemy I can’t trust. Won’t trust. But when the not-so-simple job goes sideways, I’m trapped. Bound to the very creature I despise. Now I need to decide how much of my body, or my heart, I’m willing to risk for vengeance?
