Grief

Thousands are dead. Lady Champion Bethany thought she'd given everything in the fight against Magic. She was wrong. When the deaths of those closest to her shake her already crumbled world, she doesn't wilt and die. She still has one thing left to gain even now: Revenge.

Prophecy or no, half-goddess or not, Bethany vows to bring order back to the world by the edge of her blade. No matter who she must defy. No matter what stands in her way. No matter who must die. For what they've done to her, all will pay.
