Sadie Stormbrew is a sixteen-year-old psychic witch who can read minds. She leads a socially detached lifestyle and has a cynical view of life and humanity. Lem Baxter is a scholar with hyperthymesia, and Millie Bell is an illusionist, both are also on the outer fringes of high school society. When a series of gateways to the underworld release demon spawns and cause unexplained disappearances or deaths, they develop a relationship to uncover how to close it among the many other unfolding mysteries.

Their uncanny abilities and neurodivergent minds enable them to notice what no one else can, but can they save their town on the brink and themselves when they become trapped in the underworld? Can they juggle their academics and, soon, their romantic triad relationship as creatures from these hidden worlds follow them while they try to define what a normal life is?
