Servant of the Dragon — David Drake

Return again to the world of the Isles in Servant of the Dragon, a world with hundreds of warring kingdoms without a single overlord for many centuries. Now the sources of magic are reaching a thousand-year peak, and the present generation of sorcerers is the most powerful in the millennium. Follow the small band of heroes and heroines as they journey across these landscapes, these seas, to find their loves, their destinies, and--for one--a crown.
