Firefly #12, Firefly

The conflict that began with Mal and Boss Moon has become a war, tearing the planet apart. As Mal sues for peace, he is reminded that saving the day always comes at a higher price than expected. Year one of the all-new Firefly series concludes here—and you won’t believe what waits on the other side of the new Unification War.
