"What happens one evening when Mayor Kligore forgets to restart Sleepy Hollow's Halloween curse and loses his grip on the town for a day? It snows! Everyone is excited when they awaken to three feet of the fresh, snowball-quality white stuff. It's the first wintery free day the kids can remember. But when an epic snowball fight between good and evil breaks out, Harry Moon knows Halloween never left at all."--Back cover.
