A thousand years since humans shipwrecked on Immortaland, the balance of the world changes. Dark times approach, and the Immortals are restless.

The Kingdom of Paradis was destroyed thirteen years earlier, and the Kingdom of Flint was invaded and conquered by the Kingdom of Vegar, supported by Dracodemkin and his demons. Now Vegar X wants the whole world, but first he needs to conquer Gwenolé, the first human town and capital of the Land of the White Birches. His advance clashes with armed patrols, mounted on dragons, called Defenders.

Adfric, crown prince of Flint, comes out of hiding to join the Defenders with his dragon, Gold-o-rak. The Teeth of the Dragon might be long gone, but the Defenders, untrained and non-elite warriors, can match their long lost skills. Can Adfric and the Defenders not only stop the Maleficent Alliance, but also recover the Kingdom of Flint?

The dragon riders are back and ready to fight! A gripping story of war, magic and revenge.
