In the vein of The Borrowers and The Indian in the Cupboard, this is an imaginative, irresistible, and incredible exploration into what happens when one boy discovers a kingdom of tiny people. The day before summer vacation, Max's closest friend at boarding school disappears, leaving behind his amazing model collection and a handful of sand on his bedroom floor. Like Max, the eccentric janitor Mr. Darrow is a genius at building tiny models. Eight weeks later, Max finds that the sand has magically transformed into a whole desert kingdom—filled with millions of tiny people! Max wears hearing aids, and they allow him to hear the ant-sized people. There's a boy named Luke who's about to become king. But when Max appears, he plunges their world into chaos. Luckily, Luke has two strong allies: Ivy, a fearless girl, and Luke's trusty steed—a flea. While Max and his new friend Sasha fight to protect the Floor from their evil headmaster, Luke must fight to save it from being destroyed by all-out war.
