The dragon Wearle is deeply divided because of the human boy, Ren, who has bonded with a pair of baby dragons and developed extraordinary new powers; but the war with the humans is not really over, and the humans have a mysterious new leader, Tywyll, who plans to lead his followers back into dragon territory--and unknown to both sides an ancient power is beginning to stir.

The coming of the dragons has upset the balance on Erth, and now other creatures, the wild Gibbus, and the Wyvern, are being drawn into the conflict between dragons and humans; while the dragons Gabrial and Grendel guard the young dragonets in their care, and the human boy, Ren, struggles to control his new powers, the world seems to be coming apart around them--and the firebirds are manipulating the threads of destiny.
