Summary from the publisher:
Han Solo should be basking in his moment of glory. After all, the cocky smuggler and captain of the Millennium Falcon just played a key role in the daring raid that destroyed the Death Star and landed the first serious blow to the Empire in its war against the Rebel Alliance. But after losing the reward his heroics earned him, Han’s got nothing to celebrate. Especially since he’s deep in debt to the ruthless crime lord Jabba the Hutt. There’s a bounty on Han’s head—and if he can’t cough up the credits, he’ll surely pay with his hide. The only thing that can save him is a king’s ransom. Or maybe a gangster’s fortune? That’s what a mysterious stranger is offering in exchange for Han’s less-than-legal help with a riskier-than-usual caper. The payoff will be more than enough for Han to settle up with Jabba—and ensure he never has to haggle with the Hutts again.
All he has to do is infiltrate the ultra-fortified stronghold of a Black Sun crime syndicate underboss and crack the galaxy’s most notoriously impregnable safe. It sounds like a job for miracle workers . . . or madmen. So Han assembles a gallery of rogues who are a little of both—including his indispensable sidekick Chewbacca and the cunning Lando Calrissian. If anyone can dodge, deceive, and defeat heavily armed thugs, killer droids, and Imperial agents alike—and pull off the heist of the century—it’s Solo’s scoundrels. But will their crime really pay, or will it cost them the ultimate price?
