Now a rogue group of Knights have split off to deal with the Yuuzhan Vong on their own. Luke Skywalker must stop them -- any way he can -- before they fall to the Dark Side.While Luke struggles to keep the Jedi together, Knights Jacen Solo and Corran Horn set out to learn some kind of secret that might be used to undermine the enemy. With a team of commandos they slip onto Garqi, an occupied world. If they are discovered, the Jedi will fall, and the New Republic will die...
