Angel Fire by Marie Johnston

He doesn’t have to like his new mate, even if she is the only angel to accept him.

Bryant should’ve behaved himself. Now he’s been ordered to find a mate. Easier said than done when a bloke like him looks the way he does in a realm full of angels. He’d rather be fighting the good fight in the human realm. But mating the ravishing female that claims him shouldn’t be a hardship. If only her father wasn’t the reason for his scars.
Perhaps mating the surly, scowling warrior wasn’t Odessa’s best idea. But she’s committed, and he’s…frustrating. Enticing. Carrying a grudge she knows nothing about. Yet when her boss winds up dead and she’s attacked, he’s there to save her.
Digging into the danger Odessa’s facing uncovers an ambitious plot against the realm. Good thing Bryant’s a persistent guy. He’ll stick to Odessa’s side and keep her safe, all so he can let her go in the end. Because one thing he’s learned about the down-to-earth angel is that she deserves better than him.
Except Odessa doesn’t want to be rid of the loyal warrior. But that’s an argument for a day when someone’s not trying to kill them.
