Star Wars Ylesia by Walter Jon Williams

The source provides excerpts detailing a major confrontation between the New Republic and the Yuuzhan Vong, specifically focusing on the Battle of Ylesia. Key elements include a meeting between the Yuuzhan Vong Supreme Overlord Shimrra and the traitorous Thrackan Sal-Solo, who is installed as the collaborationist President of Ylesia and Commander in Chief of the Peace Brigade. Separately, the text follows a group of Jedi, including Jaina and Jacen Solo, and military officers like Admiral Kre'fey, as they plan and execute a raid on Ylesia to dismantle the collaborationist government, culminating in a fierce ground and space battle where they capture both Sal-Solo and the self-proclaimed New Republic Chief of State, Pwoe, before barely escaping a Yuuzhan Vong counterattack. The narrative highlights the intense combat, the strategic planning, and the personal struggles and relationships among the Jedi forces during the war.
