"Is it true you can eat souls?" "Do you want me to tell you what yours tastes like?" Scarlet Radke has never been normal. Abandoned by her family as a baby and raised by an eccentric traveling adoptive mother, Scarlet is no stranger to moving around. As one of the only humans with a Demon Key, Scarlet travels between the Human and Demon Worlds, belonging to both yet neither. But, just when she thinks she finally has everything figured out, her life turns into a whirlwind of chaos and blood. An ancient power is dormant inside Scarlet, and the witches will do anything to take it from her. Will she be able to keep those she loves out of the crossfire or will she lose everything she holds dear--including her sanity?
