After his father returns from treatment for addiction, highschooler Vish -- lover of metal music and literature -- is uncertain what the future holds. It doesn't help that everyone seems to know about the family's troubles, and they stand out doubly as one of the only brown families in town. When Vish is mistaken for a relative of the weird local bookseller and attacked by an unsettling pale man who seems to be decaying, he is pulled into the world of the occult, where witches live in television sets, undead creatures can burn with a touch, and magic is mathematical. Vish must work with the bookstore owner and his mysterious teenage employee, Gisela, to stop an interdimensional invasion that would destroy their peaceful town. Bringing together scares, suspense, and body horror, The Grimmer is award-winning author Naben Ruthnum's first foray into the young adult genre. This gripping ride through the supernatural is loaded with vivid characters, frightening imagery, and astonishing twists, while tackling complex issues such as grief, racism, and addiction.
