Star Wars Darksaber by Kevin J. Anderson

In a wild and battle-scarred galaxy, assassins, pirates, smugglers, and cutthroats of every description roam at will, fearing only the professional bounty hunters-amoral adventurers who track down the scum  of the universe...for a fee. When Darth Vader seeks to strike at the heart of the Rebellion by targeting Han Solo and the Millennium Falcon, he calls upon six of  the most successful-and feared-hunters, including the merciless Boba Fett. They all have two things in common: lust for profit and contempt for life... Featuring original stories by Kevin J. Anderson, M. Shayne Bell, Daniel Keys Moran, Kathy Tyers and Dave Wolverton.
