Roxy Nouvelle understands the art of deception. The daughter of a world-renowned magician, Roxy has inherited her father's talents - and his secret life as a jewel thief. She loves the thrill of the game and can take care of herself.
Roxy is smart and resilient, but she has one weakness: Luke Callahan, a sexy escape artist with a roguish reputation. Five years ago they fell into a passionate affair - but then, true to his art - he disappeared, leaving Roxy broken hearted and furious.
Now Luke is back, trailing secrets and danger in his wake. Why did he run out on Roxy all those years ago? And can she ever trust him again?
