Ruined her innocence

Fallon Bayliss, a young, successful painter from New York, has nightmares, and some parts of her memory are missing. One night, she gets abducted by Sean, a vampire. And that brings her to the very beginning, first to London where she worked as a waitress, and then back to Rome.

Remembering she spent the last year and a half there as that vampire's pet, his sex slave, under the false identity. And all the things he has done to her recall the awful pain, realizing she both hates and desires him.
