Roman by Grae Bryan

Danny Kingman is used to fending for himself. Working nonstop as an ER nurse to pay for his mother’s care, he’s been putting his own life on hold since he can remember. But when an unbelievably hot, strangely intense man saves him from a mugging, Danny has a feeling everything is about to change. Especially when that man suddenly pops out a pair of fangs.
Roman Mourier has been wandering aimlessly for decades, waiting for the inevitable day when the last of his humanity leaves him, and the demon inside him takes permanent control. He doesn’t believe in fated mates, or the myth that there’s a soul out there that could tether his humanity to him. Until he feels a strange pull to the lovely young man at the hospital, and hope stirs in him for the first time.
But Roman has demons other than just the one inside him. Is he strong enough to keep Danny safe from the past that haunts him? He knows one thing for sure: now that he’s found his mate, he will do anything to keep him.
