The New Jedi Order Sourcebook

From the back cover: "There's a time to run and a time to stand... The Yuuzhan Vong have shattered the New Republic's promise of peace throughout the galaxy. System by system, they bring death and enslavement to all they encounter. Even the Jedi have failed to slow the merciless advance of this dark tide. As this terrible threat from beyond the galaxy's edge pushes closer to Coruscant, the need for great heroes grows even more dire."
