Firefight, authored by Alex Wheeler and published in September of 2009, represents the fourth book in the Star Wars: Rebel Force collection.
The lethal killer X-7 had a perfect record of mission success--that is, until his most recent assignment.
Now exposed and without weapons, he barely manages to flee from the Rebels, escaping with his life but little else. Though his disguise might be compromised, he refuses to go back to Commander Rezi Soresh before his objective is neutralized. He's devised a fresh strategy for this attempt: recruiting six of the most skilled pilots throughout the galaxy – all of them self-serving mercenaries driven solely by profit – and unleashing them against Red Squadron.
X-7 is relying on the mercenary nature of these pilots to maintain control. However, one of them is hiding a secret, and this secret could spell disaster for X-7's success.
