Dawn till Dusk by Tyffany Hackett

He doesn’t want to be saved. She’s determined to save him anyway.

Pain and hatred consume Tarik, the hot-headed Fae whose addiction to fighting shifters could be the death of him. Stuck in a city ruled by dragons, seeking vengeance is his only mission.
As a shifter, and the city’s Night Enforcer, Reagan’s job is to stop him. She quickly learns that trouble follows him at every turn, and keeping him alive leads her to make decisions that may have deadly consequences.
When a disastrous event forces these long-standing enemies to unravel a sinister plot, prejudice must be pushed aside. And lurking beneath the hatred is something neither of them are prepared for.
