"Everyone at Unicorn School is excited for the upcoming dance party, including Mira--even though her unicorn, Dave, loves doughnuts more than prancing. But before the dance, Mira and Dave have to go on a very special quest with their classmates--a quest that threatens to get wildly out of control. Will Mira and Dave make it out of the Crystal Maze Mine in time to hit the dance floor?"--Amazon.com.
