Gregor, age sixteen, finds a tunnel to the Underland from his farmhome in Virginia. He travels to the Underland, only to find that this section is much different then the rest. Evolved dinosaurs live in the Uncharted Lands, and want the rest of it back…

Terrormaw the Traitor has born a white rat. Every rat in the Underland is buzzing with this news. And soon the humans are too. Will the Warrior be summoned to deal with this threat once again? ..Some minor swearing and violence..

Father said nothing, merely stood there and studied me for a long time. Finally, after many minutes had gone by, he spoke, slowly and sadly. "Ripred, I think that you might be a rager."

Five years after he has last seen the Underland, Gregor is living a hard, bitter life in the shells of New York City. When an unexpected visit from an old friend turns into a deadly quest, Gregor must decide what comes first: love or life.
