The Six Crowns: The Ice Gate of Spyre by Allan Jones

The valiant hedgehog Trundle's quest for the Crown of Ice leads him and his crew to the sacred island of Spyre. According to legend, only the Oracle can find the crown, and Trundle's spirited friend Esmeralda Lightfoot is convinced she's the chosen one.

Spyre is full of wonders—and danger—from its low, swampy jungles to its soaring, icy mountaintops. And as Trundle, Esmeralda, the squirrel troubadour Jack Nimble, and their new companion, a wild and crazy hare, make their way through a monastery of fighting llamas and a nest of hungry snow snakes, they discover that nothing on this extraordinary island is as it seems.
