Dragon Rule by E E Knight

The source material comprises promotional reviews praising the author's compelling world-building and characterization, alongside narrative excerpts focusing on the political machinations within a draconic empire. The central conflict revolves around the Copper (RuGaard), the ruling Tyr of the Dragon Empire, who attempts to solidify his human alliances by prosecuting a war against the Pirate Lords of Swayport. His sister, Wistala, is appointed Queen-Consort and struggles to manage diplomatic challenges and defend the Lavadome stronghold from a sudden, violent attack by the Wheel of Fire dwarfs. Ultimately, the Tyr is betrayed by rival Protectors, NiVom and Imfamnia, leading to a successful coup that removes him from power and forces him and his siblings, including the reluctant Protector AuRon, into a precarious exile. These events establish a period of profound political uncertainty and civil strife within the powerful dragon hierarchy.
