Curse of the Reaper's Blood

He is the son of the world's most terrifying monster, cursed with a bloodlust he can barely control. She is a holy hunter sworn to eradicate his kind. After escaping the magical prison that held him for a decade, Kaelen meets Elara, the one woman who could be his salvation—or his executioner. When a greater evil rises, they are forced into an unholy alliance. To save the world, the hunter must trust the monster, and the monster must trust himself not to fall for his killer.
