*Servant of the Dragon* is a high-stakes fantasy novel set in David Drake’s Lord of the Isles universe, following a world where mortal rulers and sorcerous powers beyond ordinary experience shape the fate of distant realms. When ancient magic and restless spirits begin to unsettle the known order, a scattered group of heroes must confront dangers that test loyalty and command under supernatural pressure. The novel moves through shifting realms and moments in time, bringing together wizards, warriors, artifacts, demons, and a dragon into a sweeping adventure that can be read on its own while rewarding readers familiar with the earlier books. Drake’s style emphasizes decisive action and martial stakes, giving the plot a mythic scale as it moves across magical and political boundaries.
