It's In The Blood

She made him.now he's keeping her. Blurb:Taneka has lived for centuries by three unbreakable rules: feed, move on, and never look back. She has kept those rules across five cities and more lifetimes than she bothers to count, one night she walked into a Harlem jazz club and caught a scent that stopped her cold. It was her scent on a man who should have been dead back in 1948. Raymond Hayes was supposed to be easy.
One night, one alley, one clean exit, but Raymond survived Taneka's attack and then built an entire life from the side effects she left behind. Her thought was to finish what she started so long ago, but Raymond's intention overruled what she planned when he realized who she was.
