Sage has lived her entire life sheltered inside the Borderlands, free from any mythical creatures. Taught to hate their very existence, Sage has never considered the possibility that she has a mate. She doesn't even know what that means. However, all that changes when one of her good friends drags her outside the Border for a night of fun. Only, fun soon turns to turmoil when Sage realizes that her sheltered life will never go back to how it was before the notorious Theo Sloan claimed her as his.
