This Inevitable Ruin (hardcover) Matt Dinniman

Nine armies, each led by rich and powerful aliens from across the galaxy. Each team has one objective: to capture and hold the castle at the very center of the battlefield. Strategy, alliances, pitched battles, and, of course, betrayal... It all makes for great fun and even greater television.
