The adventure continues in this third book of the epic multiplatform fantasy series. 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.

Four children separated by vast distances all undergo the same ritual, watched by cloaked strangers. Four flashes of light erupt, and from them emerge the unmistakable shapes of incredible beasts - a wolf, a leopard, a panda, a falcon. Suddenly the paths of these children - and the world - have been changed forever.

Strange things are happening at the frozen edge of the world. Conor, Abeke, Meilin, and Rollan have crisscrossed Erdas in their quest to stop the ruthless Conquerors. Only the four of them, supported by the gifts of their legendary spirit animals, have the power to defeat an evil takeover. While chasing down a lead in the cold North, the heroes arrive at a quiet village where not everything is as it seems. Rooting the truth out of this deceptively beautiful place won't be easy - and the team is already out of time. The Conquerors are right behind them.

The sun is shining in the Hundred Isles, and yet the path forward seems crowded with shadows. Conor, Abeke, Meilin, and Rollan have traveled across the world, seeking a set of powerful talismans in order to keep them from enemy hands. Throughout their journey the young heroes have been hounded by pursuers who always seem to know just where to find them. Now they know why…
