Familiar Disney characters appear in new tales with a spooky edge.With their school closed because of nearby wildfires, Billie and Tim are spending their day at the Walt Disney Archives in Burbank, California. The book uses what Disney fan Billie is reading as a springboard, weaving together the present day and the fairy tales Billie and Tim slip into, as in the story "The Spirit Hunter," about the demon from Fantasia. When Tim disappears into a mirror he finds in the archives, Billie follows him on an adventure through dangerous Disney storylines with villains like Ursula and the Headless Horseman. Larson's illustrations are eerie and beautiful, and they also help readers track the threads of the storyline. All of the action that takes place in present-day Burbank is typeset in white against a solid black background. When Billie and Tim are in the world of Disney tales, there are ornate, themed borders surrounding each page along with a smattering of illustrations. One especially stunning full-page illustration depicts a skull with a brilliant diamond eye. The story gets a bit murky toward the end, becoming a confusing fumble through mirrors and timelines. One illustration shows Billie as a Black girl; most other characters are assumed White.Not just for fans of Disney; chilling and compelling despite a puzzling plotline. (Paranormal. 8-12)
