“Equal parts J. K. Rowling, Douglas Adams, and Shel Silverstein . . . a work of monumental silliness” from the author of The City of Dreaming Books (The Washington Post). Rumo is a little Wolperting who will one day become the greatest hero in the history of Zamonia. Armed with Dandelion, his talking sword, he fights his way across Overworld and Netherworld, two very different realms chock-full of adventures, dangers, and unforgettable characters: Rala, the beautiful girl Wolperting who cultivates a hazardous relationship with death; General Ticktock, the evil commander of the Copper Killers; Ushan DeLucca, the finest and most weather-sensitive swordsman in Zamonia; Volzotan Smyke, the corpulent Shark Grub; Rolv of the Forest, a Wolperting who can pass through the White Fire; Yggdra Syl, the guardian of the Nurn Forest and its talkative animals; Professor Abdullah Nightingale, inventor of the Chest-of-Drawers Oracle; and, the worst of luck, the deadly Metal Maiden. “There are weird and wonderful fantasy creatures and astonishingly original settings.” —The Guardian “Exuberant . . . Full of sly humor, this rambunctious novel will appeal to fans tired of the usual epic fantasy.” —Publishers Weekly (starred review) “A brilliantly imagined, well-executed jaunt through strange lands full of wild characters.” —Booklist “Cross Lord of the Rings with Yellow Submarine, throw in dashes of Monty Python, Douglas Adams, Shrek and The Princess Bride, season with more serious fare such as The Tin Drum and The Odyssey . . . part of the pleasure of reading it is to see what echoes will next bounce off its crags.” —Kirkus Reviews
