Book One Water and more

The world nearly ended a hundred years ago, when the Fire Nation originally tipped the world's balance. A century later, there are still people fighting, but hope is running out. At least, until one boy makes a stupid comment to his sister and his cousin, and they (rightfully) blow up at him, exposing a mystical, hidden iceberg... One with the Avatar inside. Oh, and his friend.The resulting light was seen by a specific burned Prince, who's been adrift from his nation for four years while his sister was being groomed by their asshole of a father. At least the Prince has his wonderful, tea-loving Uncle. Who may or may not be part of an ancient, powerful hidden group with ties around the world. Shush, it's a secret.Hijinks ensue as people try to learn, to impress the gravity of the situation on the Avatar, to cause chaos, to find love, to fall out of love, to slap jerks, steal, and more!
