"For Tinker Bell and the other warm season fairies, the Winter Woods remains a mysterious and forbidden place. Warm and cold fairies are not allowed to cross into each other's realms, to avoid risking the health of their fragile wings. Burning with curiosity, Tink sneaks over the border into winter--and something extraordinary happens: her wings begin to sparkle and glow. Tinker Bell searching for an explanation then meets Periwinkle, a frost fairy whose own wings sparkle and glow too. With the help of a wise old fairy, Tink and Peri discover they share a wonderful connection! And when a terrifying freeze threatens to destroy the Pixie Dust Tree, Tinker Bell and Periwinkle unite to see if they can save their world!" -- page 4 of cover.
