From the description:
"Fifteen years ago a young Colorado Springs police officer arrested a teen runaway accused of aiding a convenience store robbery and attempted murder. She was innocent, but still served prison time briefly. Her testimony sent the real thief to jail for much longer. Now she’s a young widow raising a son, and the man she put in prison is free and seeking revenge. She moves to a home in a new neighborhood—then learns that her next-door neighbor is the by-the-book officer who arrested her. Now he’s a Colorado Springs P.D. Lieutenant. Like it or not, he may be the only one who can protect her and her son from the past he helped create. "
