Star Wars - The New Jedi Order - Dark Tide II - Ruin

the long version

The alien Yuuzhan Vong have launched an attack on the worlds of the Outer Rim. They are merciless, without regard for life - and they stand utterly outside the Force. Their ever-changing tactics stump the New Republic military. Even the Jedi, once the greatest guardians of peace in the galaxy, are rendered helpless by this impervious foe - and their solidarity has begun to unravel.While Luke struggles to keep the Jedi together, Knights Jacen Solo and Corran Horn set off on a reconnaissance mission to the planet Garqi, an occupied world. There, at last, they uncover a secret that might be used to undermine the enemy - if only they can stay alive long enough to use it!From the Paperback edition.
