Warrior Fire by Marie Johnston

Sandeen’s a demon that did the impossible. He busted out of the underworld in his own form and roams the earth. His black wings and curved obsidian horns make it hard to blend in, but he hasn’t survived this long without being crafty. Just so happens, he knows about an empty cabin in the middle of Montana. Solitude. Peace. No need to worry about getting shanked as he sleeps. Until a persistent angel warrior hunts him down.

Harlowe’s world has turned upside down. Her best friend lost her wings because of a mind-blowing secret. Then a hauntingly handsome demon got away from her. All she can do is throw herself into her job and that involves hunting down the demon. Sandeen can’t hide. Forget his downy soft wings and the horns her palms itch to caress, his looks and inability to stay out of trouble will put him back on her radar.

Finding Sandeen was supposed to be the mission. Getting captured by him is an unplanned complication. Softening toward him could cost her everything. Sandeen risks his hard-earned freedom by keeping Harlowe alive, and it’s not long before they learn they have more problems than the growing attraction between them. Harlowe’s not the only one hunting Sandeen.
