The Comet at the End of Summer

Synopsis

For a hundred years the Fire Nation has burned its way across four nations, and the one person born to stop it has been missing since the war began. When a water tribe girl breaks open an iceberg and finds a boy asleep inside, the light of his waking shoots into the sky and is seen by a banished prince who has staked everything on capturing him. The boy can bend air. He must master water, earth and fire before a comet returns at the end of summer. He has never seen a war, and everyone he ever knew is already dead.
