When frost fairy Periwinkle travels too close to the forbidden border where Spring meets the Winter Woods, she unknowingly discovers a thread of a lost magic. And, for the first time, she begins to dream. While Periwinkle’s dreams start sweet, they slowly morph into more disastrous visions of the Pixie Dust Tree—the life source for all of Pixie Hollow—destroyed. Soon Periwinkle is confronted by a sparrow man who knows two one, that Peri has been dreaming, and two, that the Winter Woods is in terrible danger.
