Yorath the Wolf — Cherry Wilder

Yorath, the son of a royal prince, was born with a deformity that marks him for death. The court physician saves him by convincing his family that he died shortly after birth and takes him to a distant forest where he thrives, unaware of his birthright and the dark prophecy that looms over him. But as he grows to manhood, Yorath can't avoid being drawn into the violent conflict that plagues the land. Becoming a soldier, he rises through the ranks until he becomes a reluctant combatant in the struggle for the throne.
 
Even as Yorath wields the power of a kingmaker, the ways of the court are as much anathema to him as the brutality of war. If he is ever to escape the violence and machinations he so despises, he has but one choice: He must confront his heritage or lose the land he has come to love and the peace he so cherishes.
