The adventure continues in this sixth book in the New York Times best-selling series.

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…

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 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 have discovered that they have spirit animals - a rare bond between human and animal that has launched them on a quest to save their world. The team heads to the forests of Eura, where another Great Beast is hidden. At first Conor is excited to return to his old home, but when the four young heroes are betrayed by a familiar face, the hunt for the Great Beast becomes a race for their lives. But the real danger may be lying just ahead....

Something ancient and evil has awoken from beneath the world of Erdas. Shrouded in shadow and older than memory, just a sliver of its power can destroy with a touch. Even the spirit animal bond, the sacred link between humans and animals that keeps Erdas in balance, is under threat.

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.
