Wedge's Gamble: Star Wars Legends (X-Wing) - Michael A. Stackpole

The X-wing pilots of the Rogue Squadron, headed by Wedge Antilles, have a new target--Coruscant, the center of the Empire. But before a full attack can be mounted, someone must infiltrate the Imperial stronghold for vital intelligence information, and risk betrayal and capture by a ruthless warlord called Iceheart--emperor now in all but name!
Sleek, swift, and deadly, they are the X-wing fighters. And as the battle against the Empire rages across the vastness of space, the pilots risk both their lives and their machines for the cause of the Rebel Alliance. Now they must embark on a dangerous espionage mission, braving betrayal and death on the Imperial homeworld to smash the power of a ruthless foe

It is the evil heart of a battered and reeling Empire: Coruscant, the giant city-world from whose massive towers the Imperial High Command directs the war. The Rebels will invade this mighty citadel in a daring move to bring the Empire to its knees. But first Wedge Antilles and his X-wing pilots must infiltrate
Coruscant to gain vital intelligence information. Capture means death, or worse--enslavement by the vicious leader known as "Iceheart," Ysanne Isard, now
Emperor in all but name. And one of Rogue Squadron's own is already her slave, a traitor hidden behind a mask of innocence, working to betray both colleagues and the Rebellion itself.
