The Wolf by Peggy L Henderson

Connor Moran lives his life for himself, answering only to the laws of the land to survive. His skills as a woodsman and expert tracker make him the perfect candidate to discover what has happened to a young woman who went missing several years ago. Uncovering the details of her story takes him into unchartered territory, not only in the mountains, but maybe even his heart.
Louella Leigh has endured unspeakable horrors in the years since being taken captive. She has learned how to overcome her fears and rise above weakness to exist peacefully among the people who will never accept her as one of their own. When a man arrives to bring her back to her former life, she struggles to understand exactly where she belongs.
Traveling together for months exposes the deep similarities that Connor and Ella share. Strength and self-reliance, bravery and endurance are traits found within the lone-wolf characteristics of both. Will the reality of their differences threaten to tear them apart once Ella returns to her life of luxury?
