Janner, Tink, and Leeli Igiby, the Lost Jewels of Anniera, are hiding from Gnag the Nameless in the Green Hollows, one of the few places in the land of Aerwiar not overrun by the Fangs of Dang. But there's a big problem. Janner's little brother--heir to the throne of Anniera--has grown a tail. And gray fur. Not to mention two pointed ears and long, dangerous fangs. To the suspicious folk of the Green Hollows, he looks like a monster.

But Janner knows better. His brother isn't as scary as he looks. He's perfectly harmless. Isn't he?

Full of characters rich in heart, smarts, and courage, The Monster in the Hollows is a tale children of all ages will cherish, families can read aloud, and readers' groups are sure to enjoy discussing for its many layers of meaning. Extra features include new interior illustrations from Joe Sutphin, funny footnotes, a map of the fantastical world, inventive appendices, and fanciful line art in the tradition of the original Frank L. Baum Wizard of Oz storybooks.
