Dante Hart is a hired gun.

Trained to kill, he always finishes a job -- by any means necessary.

Then, he saw her.

Lucy Vaughn. The beautiful dancer. His mark's only daughter.

She'd do anything to save her father, including spend the night with the man sent to kill him.

Only one night, she said.

But Dante had other plans.

Lucy spent the night with the devil. Now, he won't let her go.

Not without giving him the one thing she could never give a monster like him: Her heart.
