After their victory in the Battle of Yavin, the Rebel Alliance make plans to set up a new base on the planet Hoth. Han and Leia set off to gather supplies for the base, but Leia is troubled when she encounters a group of Alderaanians who survived their planet’s destruction but had resorted to living as pirates. Razor’s Edge is a great Leia-centered story leading up to The Empire Strikes Back.
Times are desperate for the Rebel Alliance. Harassment by the Empire and a shortage of vital supplies are hindering completion of a new secret base on the ice planet Hoth. So when Mid Rim merchants offer much-needed materials for sale, Princess Leia Organa and Han Solo lead an Alliance delegation to negotiate a deal.
But when treachery forces the rebel ship to flee into territory controlled by pirates, Leia makes a shocking discovery: the fierce marauders come from Leia’s homeworld of Alderaan, recently destroyed by the Death Star. These refugees have turned to pillaging and plundering to survive—and they are in debt to a pirate armada, which will gladly ransom the princess to the vengeful Empire... if they find out her true identity.
Struggling with intense feelings of guilt, loyalty, and betrayal, Leia is determined to help her wayward kinspeople, even as Imperial forces are closing in on her own crippled ship. Trapped between lethal cutthroats and brutal oppressors, Leia and Han, along with Luke, Chewbacca, and a battle-ready crew, must defy death—or embrace it—to keep the rebellion alive.
