Sheriff Mal Reynolds has a new partner--a law enforcing robot from the Blue Sun corporation, who doesn't care about motives, mercy, or anything other than enforcing the law--no matter the cost. The Blue Sun Corporation has helped run the 'Verse from the shadows for years, but they're ready to step into the light and take over. If Mal wants to keep his job and protect his sector, the smart move would be to play by their rulebook. But for Mal, there's really one choice--reunite the crew of the Serenity for one last impossible job to save the 'Verse. New York Times best-selling writer Greg Pak (Darth Vader) and acclaimed artist Dan McDaid (Judge Dredd: Mega-City Zero) launch Mal & the crew of Serenity into their biggest war yet, officially continuing Joss Whedon's acclaimed series. Collects Firefly: Blue Sun Rising #0 and Firefly #21-22.
