Gray is dispatched to the port of Fleming on the Endless Sea to investigate the sudden appearance of rogue green dragons. Stinson, Gray’s nemesis since childhood, is assigned to accompany him into the drylands and beyond. Their partnership is contentious, but Gray discovers information that changes everything—and threatens the end of the Dragon Clan. His actions might upset the delicate balance of power, and end a truce. Worse, war is coming and the king is unprepared, perhaps even traitorous.
