Finding the Great Cold Queen was only the beginning. Her aching heart triggers a great freeze that crawls across the mountains all the way down to Tickletoes River, threatening the lives of everyone in Fairy Glade. While Princess Thamilla sets out on a treacherous quest to rescue the water sprites, Ruse and Buttons race through the dark, freezing forest to save the Great Cold Queen's children and bring peace to her heart. Escaping poppens, dodging creatures, and finding new allies, the two fairies must save the young dragons if they wish to save the land.
