Magic, danger, and adventure abound for messenger Karigan G''ladheon in the third book in Kristen Britain''s New York Times-bestselling Green Rider fantasy series • "First-rate fantasy." —Library Journal
More than a thousand years ago, the armies of the Arcosian Empire, led by sorcerer Mornhavon the Black, crossed the great sea and tried to conquer the land of Sacoridia using terrible dark magic. Eventually, Mornhavon was captured, and his evil spirit imprisoned in Blackveil Forest.

For there were Arcosian soldiers who survived the Long War, and the descendants of those ancient enemies spent generations honing their powers of dark magic—a force against which the Sacoridians have no defense....
