When world-travelled Finlay Fisher is forced to return to the small town of his birth he believes life will be boring, but less than a day after arriving, Finn, his cousin Lincoln, friend Auburn Rivers and many of the local teenagers are abducted. Taken to the strange water-world of Aqualtia and sold into slavery, the teens are forced to ride ferocious dragon-like beasts in bloody fights to the death for the entertainment of their new masters.
Separated from the others, Lincoln and Auburn face even greater ordeals when they are given to Assidian, Aqualtia's evil king and his witch. They are also trained in the hope that they will recover Aqualtia's most important and long-lost artefact, a stone that can give life to a planet, or destroy it.
With the planet on the brink of destruction the Fisher boys must accept their heritage and fight, but who will win? Can the teens survive this harsh world and its cruel people, and could it be possible that slaves could save the dying world and the people that scream for their death?
