Winter is the most daring of the seasonal Sparkle Sisters. She loves to play with her sisters, Autumn, Spring, and Summer, but her very best friend is her pet polar bear, Flurry. He's the perfect companion for sledding, ice skating, and all kinds of wild escapades. When Winter and Flurry decide to build the biggest snow fort of all time, they're surprised by a baby arctic fox. Winter loves him immediately . . . which makes Flurry very jealous. When Flurry's hurt feelings send him running to play with the Weeds, wild boys who bring trouble wherever they go, Winter will need the help of all of her enchanted sisters to get him back!
