Rumors fly of a dark power, and soon Tarn’s caravan encounters the living dead and an amnesiac mage called Gard.Forced to take refuge in the Court of the Shells, a legendary fortress in the heart of the desert, Tarn, Gard, and their allies decide to seek out the Shadow before it destroys the desert. But to confront the Shadow, Tarn needs to gather his strength. A dragon's power depends on the love and loyalty of his human hoard, but Tarn's original hoard has been dead for centuries. Before he can face his most ancient enemy, he must win the trust of new followers and the heart of a cynical desert spirit.
