A betrayal he couldn't forget. A love she couldn't deny.

For Nate Dean, love is a four-letter word. As part of a secret black-ops unit, he and his brothers were engineered to be ruthless soldiers with an expiration date. They were loyal only to one another—until Nate laid eyes on the woman who stole his heart and blew his world apart. Now, as time runs out, only one person can save his family: the very woman he swore he'd never trust again.

The moment Audrey Madison spies Nate across a crowded ballroom, she can barely breathe. When he asks for her help, she can't refuse. But she has secrets of her own—secrets that, if Nate ever discovers them, may cost them both their lives.
