Gr 4–6—Eleven-year-old Charlie Laird is absolutely convinced that his stepmother Charlotte is a witch. She dresses funny, serves seriously strange food (kale pancakes), and runs a store called Hazel's Herbarium. Charlie's dad, little brother, and friends all like Charlotte and think Charlie's still grieving for his mom. He's also suffering from terrible nightmares, and living in Charlotte's crazy purple mansion isn't helping. The evil witch who stars in those nightmares threatens to follow the protagonist into the real world and kidnap his brother. Instead, he is tricked into the Nightmare World, peopled with monsters and madness: gorgons, goblins, crazy clowns, scary bunnies, tests filled with gibberish, and the monomaniacal President Fear (who also inhabits the real world as the truly terrifying Principal Stearns). But all is not what it seems, and some of the scariest creatures turn out to be sympathetic—or even allies. There are lessons to be learned about facing fears and uncovering the real enemy in this tale. Pals Alfie, Rocco, and Paige are interesting and fairly three-dimensional; most of the adults (with the exceptions of Fear/Stearns and Charlotte) are merely background. The fear is as much psychological as anything, and there's humor and a fairly high ick-factor, but relatively little violence. A good choice for elementary-aged scare-seekers.—Mara Alpert, Los Angeles Public Library
