Rachel, a former CIA agent, is trying to live a normal life. And she is trying to forget Milton Reed, the sexy scientist who was part of her last mission—a failed operation that ended with a forbidden night of passion. A year later, she still fantasizes about him. When he appears without warning and asks for her help, Rachel's attempt at a normal life falls apart and her sexual fantasies begin to materialize.

When Milton asks for help from the only person he can trust—a woman he's never been able to forget—he thinks it will be simple. They'll go undercover in a plot for revenge against Thane, a powerful, manipulative arms dealer they both should hate. But nothing is simple in Thane's decadent, dangerous world, especially when the villain sets his sights on Rachel.

The lines of trust, pleasure, and control begin to blur as Rachel and Milton discover the one thing they can never escape.
