Maggie Shayne's Embrace the Twilight

A creature of the night, Sarafina lives only for her own pleasure, but love is an emotion she has deemed forbidden. She tries to not remember a time, centuries ago, when she knew the true meaning of love. A time before she was changed by her blood curse. She has vowed to never let herself fall in love again. Even when she encounters Colonel Willem Stone at a night club, she wants only to posses him long enough to satiate her deep, passionate hunger. He is man of almost inhuman courage and defiance. He is as boldly alive as she is, yet he is mortal. The only thing stronger than the clash of their wills is the power of their desire.

When a young girl, the Child of Promise, is kidnapped by vampire hunters determined to steal the secrets of her immortality, Willem and Sarafina must put aside their struggle and combine their strengths in a rescue attempt that could cost them their very lives, and in the process they discover the most powerful force of all. Love.
