The swarm war - Troy Denning

The third and last book in the all-new trilogy that will bridge the events of the hugely popular New Jedi Order series, which has sold four million copies to date, and our upcoming 9-book epic Star Wars series to be published in 2006-2008.
With the Jedi Order splintered by conflicts of conscience, and a war erupting between the Killiks and Chiss that could spread across the entire galaxy, Luke Skywalker takes charge. His bold plan will play all sides against each other and carry those closest to him deep into hostile territory. It is also the only thing standing between the galaxy and the eternal war that his nephew, Jacen, has foreseen in visions.
For the Jedi to succeed, they must step beyond the reach of any galactic government and undermine the war-making capabilities of all sides -- and Luke Skywalker must assume his fated role as true master of the Jedi Order.
