The sixth and final book in the animal fantasy series The Six Crowns, of which Booklist said, "Evokes elements of both Redwall and Lord of the Rings." The adventuring hedgehog Trundle Boldoak and energetic Princess Esmeralda must find the final legendary crown in their quest to save their lands!

Five of the six lost Badger crowns have been found. Only one is left—the Crown of Stone. But legend has it this crown is on an island long forgotten. Will Trundle and his swashbuckling companions be able to find it on their trusty ship? With dangerous pirates hot on their trail, Trundle and his friends must set sail to an island that might not even exist. An entertaining—and funny!—tween adventure with lively black-and-white illustrations throughout. School Library Journal called the Six Crowns an "action-packed page-turner . . . that even reluctant fantasy readers will embrace."
