Kate knows two things: never run from a fight and always protect the ones you love. Whenever her loved ones are 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. 

Betrayal whisks Kate away to the Otherworld to be her human champion. Just like that, Kate loses everything: her home, her friends, her fundamental beliefs about the laws of physics. And she finds Betrayal to be an insufferable egomaniac. Betrayal agrees to return Kate home if Kate will help stop Death from taking over the Otherworld with his decrepit magic. But Kate isn’t sure she and Betrayal can stop bickering long enough to work together. 

With Death intent on dissecting Kate, Betrayal must either swallow her pride and prove to Kate she is not the villain or risk the human dying in Death’s realm. Meanwhile, Kate would like Betrayal to realize she isn’t going to grovel like the others—even if there’s something infuriatingly alluring about Betrayal. Something that makes Kate want to push the pompous smokeshow into a corner and do things to her.
