"[A] joyful tale of learning to believe in oneself and rejoicing in magic both grandiose and mundane."—Publishers Weekly

To some, the low door in Eliza’s bedroom might look like an ordinary entrance to a crawl space under the stairs. But to a believer like Eliza of the Elves, it’s the door to the Land of UnderStair, a secret hideout all her own. In that crawl space, festooned with twinkling lights, Eliza keeps her favorite book, her collections of precious items, her stuffed animals, and her new diary. And in that crawl space is another door, a teeny-tiny one that can transport Eliza to a world of tangerine sun and lemon-pudding sky, a place where flower fairies perch on every bloom and a new flower springs up whenever you pick one. But in a far corner of that world, Eliza tries to pick a strangely beautiful flower—“Nooooo!” cries her friend Poppy—and things soon go terribly awry. Can a brave, wilting Poppy rescue Eliza from beyond the hedgerow before the Demon Wind steals all the flower fairies’ scents, leaving the snapdragons with no snap? In this launch of a new series, Megan McDonald brings her well-honed flair for wordplay to delicious villains like the witches Wolfsbane and Belladonna as she follows a child with a big imagination to a different fairy realm in each book. Lenny Wen’s delightful, richly colored artwork brings Eliza’s world to life with fanciful details sure to have readers creating their own cozy retreats—and visiting magical lands beyond the door.
