7 Little Letters. Tainted Love, #0

They turned me into the faithless mistress they knew I could be and I was fine with that. Until I was sold. One night of trying to save her boyfriend's brother from a gang of criminals turned Anna's life upside down. A year later, she's let go of her past and embraced her present - kept in a luxurious penthouse by a callous billionaire to satisfy his desires. But someone else wants her, someone who will stop at nothing to possess her.
 Through a series of dark letters, Anna learns the clock on what little freedom she has is ticking down, day by day. Because for one man, as broken as she is, she's the woman who will help him ensure a dynasty of power to last generations. This short and not-so-sweet dark romance novella of young love gone wrong is the prequel to the Tainted Love series.
