The Vampire's Reckoning — Cynthia Cooke

Emma McGovern has lived her life in fear. A centuries old curse has plagued her family for generations. If she finds love, and consummates that love, Asmos a demon from the 7th realm, will claim her as his own. To remind her of his power, Asmos sends demon wolves for her each year on the night of the equinox. This year is no different, except the Cadre has sent an agent to help her. But he might just be her undoing.
Damien has one job--capture and contain the demon Asmos. He knows how powerful Asmos is, but what he didn't bargain for is the affect Emma would have on him. He cannot fall in love with her. He knows the risk, and yet, they can't stop the pull they feel toward one another. Not even when Emma learns he's a vampire, and might just be as big a danger to her as the wolves waiting at her door. Will the love they find be strong enough to fight a demon, or will it cost them both their lives?
