5 Worlds The Sand Warrior. Book 1

"Five worlds on the brink of extinction. Can three unlikely heroes save the day? Oona Lee, the clumsiest student at the Sand Dancer Academy, is a fighter with a destiny bigger than she could ever imagine. A boy from the poorest slums, An Tzu has a surprising gift and a knack for getting out of sticky situations. Star athlete Jax Amboy is beloved by an entire galaxy, but what good is that when he has no real friends? When a devastating attack forces these three kids to team up on an epic quest, it will take not one, not two, but 5 worlds to contain all the magic and adventure."--Back cover
