Nannying six children was supposed to be the toughest part of Lexie DeMille's new job. Then their massive Aspen residence was attacked and it was clear someone had a very personal vendetta to settle.

Something about her had driven her assailant into a violent rage. And that same thing blurred the parameters of Mason's detail-and would test his every survival instinct.
