Wings of Fire (Book 7) Winter Turning by Tui T Sutherland
Daring mission… or deadly mistake? Winter has been a disappointment to his royal IceWing family his whole life. When his sister, Icicle, runs away from Jade Mountain Academy, fleeing terrible crimes and possibly planning to commit more, Winter knows that they both need a second chance to make things right if only he can find her. Winters new clawmates, Moon, Qibli, and Kinkajou, wont let him make this dangerous journey alone. They don’t seem to understand that IceWings, the most superior of all dragon tribes, can fix their own problems. When their search leads the dragonets straight into Queen Scarlets vicious talons, Winter is grateful to have some help. But even the bravest dragons cant follow him to the Ice Kingdom, where hell have to face the greatest threat of all: his own family.
