Knight's Dominion (Knights of Hell #4‪)‬

Fight. Eat. Sleep. Fight some more. Chaos's world is raw, uncompromising and solitary - just the way he likes it. But when Hell's bid to conquer the earth escalates, the Knights need help. If only their best chance wasn't a beautiful demi-demon warrior who fires insults like arrows...and makes Chaos burn hotter than hellfire.

After she lost everything, Burlesque dancer Grace Paten vowed to rid earth of the demon scum murdering and enslaving her people. But one brutal, arrogant Knight stands in her way...the man who destroyed her world, the man who ignites her temper almost as much as he ignites her lust. The last thing she expects is a request to fight alongside him.

Only working together can win this deadly war. Yet Grace must keep a secret from Chaos that could not only test loyalties, but hearts as well.
