Based on: Winter turning​ by Tui T. Sutherland.

"Winter has always been a disappointment to his royal IceWing family. Now he has a chance to save his sister, Icicle, from making a terrible mistake--if he can find her. Winter's new clawmates, Moon, Kinkajou, and Qibli, insist on joining his dangerous journey. They don't understand that IceWings, the most superior of all dragon tribes, can fix their own problems. When their search leads the dragonets straight into Queen Scarlet's vicious talons, Winter is grateful to have some help. But even the bravest dragons can't follow him to the Ice Kingdom. There, he'll have to face the greatest threat of all: his own family"--Provided by publisher.
