Erdas is a land of balance. A rare link, the spirit animal bond, bridges the human and animal worlds. Conor, Abeke, Meilin, and Rollan each have this gift - and the grave responsibility that comes with it. But the Conquerors are trying to destroy this balance. They're swallowing whole cities in their rush for power - including Meilin's home. Fed up with waiting and ready to fight, Meilin has set off into enemy territory with her spirit animal, a panda named Jhi. Her friends aren't far behind...but they're not the only ones. The enemy is everywhere. In this third entry in the multi-platform fantasy series, the four friends, with the help of their animal familiars, embark on a dangerous mission to stop the dark force that threatens their very survival.
