When Stevie Mazzetti was six months pregnant, her husband and five-year-old son were shot dead in a store robbery. A killer was found and imprisoned and Stevie returned to work as a homicide cop, but things could never the same again... Years later, she receives a letter bearing the name of the man imprisoned for the crime, and her world is turned upside-down once again. Who has the letter come from? And could it be that the real killer is still at large? Her hunt for the answers will force her to confront her past once again, and send her straight into the arms of Clay Maynard - the brooding ex-cop she'd sworn to leave behind.
