Plans that have been shaped for over a thousand years will finally be executed when dragons awake and the gates between worlds are thrown open. Daniel and Freya, along with Alex, Vivienne, and the knight Ecgbryt, join together with the inhabitants of Nidergeard to confront the forces allied against them in this final volume of The Ancient Earth Trilogy. Nidergeard lies exposed and the army that the dark wizard Gad has been gathering over the past years--made from giants, dragons, trolls, and yfelgopes--is finally assembled and ready to invade the nation. All that stands in their way is the Langtorr, the last standing structure in Nidergeard, and its inhabitants. The fate of Britain--and the world--all centers around the events of a single day . . . a day when the mystery of what lies behind The Fearful Gates is revealed.
