The Star Wars Legends: Truce at Bakura

No sooner has Darth Vader's funeral pyre burned  to ashes on Endor than the Alliance intercepts a  call for help from a far-flung Imperial outpost.  Bakura is on the edge of known space and the first to  meet the Ssi-ruuk, cold-blooded reptilian invaders  who, once allied with the now dead Emperor, are  approaching Imperial space with only one goal; total  domination. Princess Leia sees the mission as an  opportunity to achieve a diplomatic victory for the  Alliance. But it assumes even greater importance  when a vision of Obi-Wan Kenobi appears to Luke  Skywalker with the message that he must go to  Bakura-or risk losing everything the Rebels have fought  so desperately to achieve.
