When a girl in a blue dress crashes the Mad Hatter’s eternal tea party, the sleepy Dormouse feels more awake than he has in a long time. He wishes he could follow her and be a part of her adventure.

And as luck would have it, a surprising twist of fate sends the Dormouse on an adventure of his own, where he must not fall asleep. For he is destined to save a magical world outside Wonderland, and it will take all his courage—and a few new friends—to do it.
