But when Coco manages to catch a glimpse of the witch Qifrey casting a spell, her revelation on the truth behind magic drastically alters the course of her life. However, Coco's curiosity pays a steep price when a disastrous spell cast in ignorance brings a tragic fate upon her beloved mother. Qifrey takes the shaken girl in, recognizing both her resolve to save her mother and her link to a group of forbidden magic heretics. Secrets are a heavy burden, and between navigating a society that views her as an uninvited guest and mastering the art of magic, Coco must give her all to prove her worth as a witch.
