The Bedroom Barter (Harlequin Presents #2442) (Foreign Affairs)

Chellie Greer is a long way from home. Penniless and without her passport, she's stuck working in a seedy club with no means of escape - until Ash Brennan walks in. What's such a powerful, irresistible stranger doing in a place like this?

Ash offers her a way out, but Chellie has to wonder exactly why he is rescuing her. Does he really want to protect her, or is there a price on her head . . . and on her body
