Hunting Lucy by Elisa Leigh

He’s a dirty talking demon. She’s his Belle of the Halloween ball.
Balor has lived a thousand years doing everything for the dark lord, but the day she’s born his life changes irrevocably.
He’s no longer tied to the darkness, but instead to the light.
Lucy is too good for him. He knows this better than anyone, too bad she’s dressed to kill and he’s not letting anyone get the chance at claiming what’s rightfully his.
He’s held himself back, but what happens when he finally snaps and claims his soul mate?
