Half Dead by Annabel Chase

Lorelei Clay wants to play offense for a change. She’s tired of hiding from the past she didn’t even know she had. With a promising relationship and new friends in a small town she loves, Lorelei wants to be free to live life on her terms, without the threat of death or capture hanging over her.
Kane Sullivan hasn’t exactly been hiding from his past—more like he moved without a forwarding address. Unfortunately for him, the boss he tried to overthrow never gave up the search.
And now the former prince of hell has been found.
Kane wants to do whatever it takes to keep his problems from endangering his found family. He knows better than anyone what Lucifer is capable of.
Lorelei is willing to do whatever it takes to protect the demon she loves, but if she can’t convince him to get in the game, they risk losing everything they’ve built together.
When the supreme demon finally makes his move, Lorelei realizes there are some nightmares that even she can’t control.
