At six years old, Martha Higden traded her fear to a demon named Erlich. The bargain promised a life without pain. Instead, it left her hollow—missing her father, her feelings, and the ability to connect with the real world. Years later, Martha inherits her father’s dangerous legacy: the ability to astral project into hidden dimensions. Alongside her best friend, Jess, Martha plunges into a surreal multiverse of slime portals, mirror prisons, and terrifying gods to find her missing dad. But every answer in these hidden worlds comes with a price, and every path leads right back to Erlich. As the darkness closes in, Martha faces a chilling question: If you bargain away your fear, pain, and shame... what exactly is left of your humanity?
