The Rebels have taken the Imperial headquarters world of Coruscant, but their problems are far from over. A killer virus called Krytos is spreading among the population, and fomenting a counter-revolution at the heart of the New Republic. At the same time, Rebel hero Tycho Celchu is on trial for treason, accused of murdering his comrade and fellow pilot, Corran Horn. Corran, however, is still alive but trapped in the secret inescapable prison of Ysanne Isard, the imperial officer whose reputation for torture and cruelty have earned her the unofficial moniker 'Iceheart.' As he fights for his freedom, the pilot discovers an extraordinary power in himself-the power of the Force!
