Saint Or Sinner by Cynthia Eden

Beware of Beauty…because she’s got the heart of a real beast.

Smart people–and monsters who know the score–fear Josephine Saint. The sexy vampire might appear to be a sensual temptation, but she’s a cold-blooded assassin. Mercy? Jo doesn’t know the meaning of the word. With each successful hunt, Jo slides one step closer to getting the promised prize that she’s coveted–her freedom. Long ago, Josephine made a deal with the devil, and now, the jerk is collecting on the final payment due him.

Find the angel…before he rips the world apart.
Her latest target is Malik, an angel who has gone dark. The fool fell and crashed hard to earth, and now he’s indulging in every sin he can find. And, bonus, the guy has every predator in the land closing in on him because angel wings are highly prized on the black magic market. It’s Jo’s job to find Malik and bring his sexy angel ass back upstairs except…

The angel is already changing…into something new and something very, very deadly.
Malik has his own mission, and it doesn’t involve being dragged back to heaven. He’s ready to lose his wings, ready to pay any price, if it means he can right a wrong from his past. He never expected for Jo to hunt him, and he knows that he won’t be able to control himself when she’s near. Because Jo–fierce vampire, deadly assassin–she’s his charge. He’s been watching over her for centuries. Watching her, and wanting her. Now that he’s earthbound, Malik can finally make the vamp his.

Can a vamp save the world? Maybe…if she can claim a fallen angel’s heart.
With every moment that Malik spends on earth, the darkness within him grows. When angels fall, they change. They become something new–and a firestorm is about to erupt from Malik. When the fire erupts, it will destroy everything and everyone in its path…His only link to sanity is Jo, and if he loses her…Malik may lose his very soul.

The hellfire is coming, and it will rage. SAINT OR SINNER…what will you be?
