Kate lives by two truths: never back down from a fight, and always protect the ones you love. When her chosen family is in trouble, Kate comes out swinging. Unfortunately, Kate doesn’t realize that her feral fighting style is just what Betrayal, the daughter of Death, has been searching for.  

Without warning, Betrayal whisks Kate away to the Otherworld, demanding Kate become her human champion. The deal is simple: help Betrayal defeat her father, and maybe Kate can return home. However, trust doesn't come easily for Kate, especially when her ally is the literal embodiment of treachery. Yet, despite Kate’s better judgment, an unwelcome desire emerges—a desire to corner the captivating villain and make her beg.
