Though Buffy has legions of fans and The Avengers is the third-highest-grossing movie of all time, many would argue that Joss Whedon’s greatest contribution to nerd culture is the Serenity universe. A moving sci-fi/western with equal parts darkness, humor, and heart, even cancellation couldn’t kill it. After the Serenity movie finished up the tale that Firefly never got a chance to finish, Dark Horse started sporadically publishing comics to bridge the gap, and loyal Browncoats have been lapping them up ever since. Now a new miniseries will be picking up the story after the movie, the six-issue Leaves on the Wind by Zack Whedon and Georges Jeanty, and it’s looking like this will be the last Serenity comic with a Whedon in the writer’s credit for quite some time. With that in mind, here’s a look at all the Serenity comics so far, how they fit into the timeline, and the leftover secrets from Firefly that they reveal. Fair warning: if you’ve only seen Firefly and the movie, this article will spoil your face off. And if you’ve never even seen Firefly, a) why are you even bothering with this article and b) for Christ’s sake go watch it right now!
