Pretty Lies. Pleasure House, #4

She told pretty lies to the wrong man and now she must give herself to him to save her sister's life. As a phone sex operator, Annette knows how to tease to get what she wants. That is, until she teases the wrong man at a club, claiming kink fantasies she doesn't really have. It must have been too much vodka and his tantalizing Russian accent. Too bad he believes her. When the Russian accidentally kidnaps her twin sister as part of an ill-fated sex game, things quickly get real.
In a desperate bid to free her twin, Annette offers herself to him in trade. Anton both terrifies and excites her, but she knows she can never trust him. His demands will push her to her limits and beyond, and this time, she can't tell pretty lies and run away. All books in the Pleasure House series are interlocking standalones and can be read in any order.
