Lone Wolf — Michael Newton

A werewolf contends with love and hunger while fighting for the Confederacy during the Civil War in this romantic fantasy.
 
Graham is on the run. Running from a civil war that he was forced into, from the beast that lies hidden within him, and from the curse that keeps him from leading a normal life.
 
When Graham meets Eliza, a mere human, he falls deeply in love. But could she possibly love him once she discovers his ability to transform into the beast? Can Graham tame the beast inside him and live a normal life, or will his secrets tear apart the growing love between he and Eliza?
