The specter of the menacing Grand Admiral Thrawn looms over Luke and Mara Jade Skywalker as they embark on a journey to recover an important piece of Jedi history.

Sometimes it seems a Jedi’s work is never done, and Luke and Mara Jade Skywalker know this only too well. Despite the bond they share in the Force, the Jedi Master and his wife are still learning the ropes of being a couple after three years of marriage—and struggling to find time together between the constant demands of duty. But all that will change when they’re united on an unexpected mission: They must pool their exceptional skills to combat an insidious enemy and salvage a part of Jedi history.

Whatever may await, the Skywalkers will not face it alone. Joining them on the strange and solemn journey are an officer of the post-Palpatine Empire escorted by a detachment of Imperial stormtroopers; a party of diplomats from a gentle alien species that reveres the fallen Jedi for saving them from bloodthirsty conquerors; and a New Republic ambassador who harbors his own mysterious agenda.

Soon enough, suspicion, secrecy, and an unknown saboteur run rampant aboard the isolated ship. But the gravest danger lies within the derelict walls of Outbound Flight, buried for half a century on a desolate planetoid. As the marooned hulk yields up stunning revelations and unexpected terrors to its visitors, Luke and Mara find all that they stand for—and their very existence—brutally challenged. The ultimate test will be surviving the deathtrap carefully laid by foes who are legendary for their ruthlessness, and determined to complete the job Thrawn began: exterminating the Jedi.
