Sword of the Scarred by Jeffrey Hall

SPFBO7

The price of becoming a legend is more than most are willing to pay. Requiem Balestone is the last of the Scarred, a group of warriors with tremendous power that when wielded leaves cruel wounds upon their skin. After a lifetime of battling monsters, he’s gathered enough scars to become a ruined version of his former self. But before he can lay down his blade, one last mission calls him to battle. A mission that pulls him into the middle of a civil war that threatens to destroy the world. And as both sides close in around him, and a mysterious evil begins to stalk the land, Requiem must decide if he’s willing to sacrifice the rest of himself to become the savior of the realm, or walk away from it for good.
