Star Wars: Before the Storm (The Black Fleet Crisis, #1)

It is a time of tranquillity for the New Republic.  The remnants of the Empire now lie in complete disarray, and the reemergence of the Jedi Knights has brought power and prestige to the fledgling government on Coruscant.  

Yesterday's Rebels have become today's administrators and diplomats, and the factions that fought against imperial tyranny seem united in savoring the fruits of peace. But the peace is short-lived.  

A restless Luke must journey to his mother's homeworld in a desperate and dangerous quest to find her people.  An adventurous Lando must seize a mysterious spacecraft that has weapons of enormous destructive power and an unknown mission.  And Leia, a living symbol of the New Republic's triumph, must face down a ruthless leader of the Duskhan League, an arrogant Yevetha who seems bent on a genocidal war that could shatter the fragile unity of the New Republic... and threaten its very survival.
