To learn if she truly is the last dairne in the world - the endling - Byx and her friends must travel into the snow-covered mountains of the country of Dreyland, where they hope to uncover the truth behind the legend of a hidden dairne colony....

There's something pretty weird going on in the woods behind Cassie's house, the place where Ax and Tobias call home. It seems the Yeerks have figured out one very important fact: Andalites cannot survive without a feeding ground....
