Solana Grey hunts the muki that haunt Supay, a land whose people are cursed to return as monsters after their human lives end. Killing them releases their souls, but forces her to endure the remnants of their grief and suffering. Driven by duty and the need to atone for her father's betrayal, she longs to escape the burden she has carried for years. When the opportunity to become Royal Demon Hunter appears, Solana sees a possible route to freedom. The role instead draws her towards a darkness with a particular claim on her soul. With loyalties pulling her back to Supay and an attraction to a man she should regard as an enemy complicating her choices, she must weigh her own escape against joining a struggle that could lead to destruction and revolution.
