Within Range — Janice Kay Johnson

If the detective was going to protect her,

He'd have to get her to let her guard down first.

Helen Boyd had thought she and her son were safe from her abusive ex-husband. Then she finds a dead woman in her house -- a woman who looks a lot like her. Detective Seth Renner suspects that Helen was the intended victim, but soon learns Helen has many secrets… He doesn't know what to believe, except that this woman and child need care and, right now, protection.
