What’s it about?

The story.

The Five Worlds are close to extinction, and the only hope is to light five ancient beacons before war and dark magic consume the galaxy. Oona Lee is a clumsy student at the Sand Dancer Academy who may have far more power than anyone expects; An Tzu is a poor boy with a mysterious gift; and Jax Amboy is a famous athlete with no real friends. When the three are thrown together, they must begin a quest that will stretch across planets, cultures and magical traditions. The Sand Warrior sets up the whole saga with high visual impact: sweeping landscapes, bright character designs, kinetic action and a rich mythology that rewards readers who like world-building. It is more intense than a cosy graphic novel, but the teamwork, friendship and classic save-the-world structure make it highly accessible for confident middle-grade readers.

Why kids love it

The specific kick is the three thrown together — Oona the clumsy student at the Sand Dancer Academy who turns out to have real power, An Tzu the poor boy with a mysterious gift, Jax the famous starball player with no friends, the five worlds dying and five beacons needing to be lit. The 5 Worlds opener for a reader who wants their Avatar: The Last Airbender as a chunky painterly graphic-novel epic.

  • Being special or chosen
  • Going on a quest
