They'll shield her newest charge...no matter what the cost. When an infant is abandoned on her ranch, foster mother Isabelle Trent will do anything for the child-even put her own life on the line. She might not know who left the little girl, but it's clear someone's after her and will kill to reach their target. With Isabelle's ranch hand, Brian "Mac" McGee, at her side, can she survive long enough to protect the baby?
