Trade paperback. Written By The B.D.H. himself Joss Whedon This companion is packed with goodness from the original script, to production artwork, stills from deleted scenes to exclusive commentary by Joss & company. It's shiny, glossy, really nicely put together and, in our opinion, a must have for the Serenity fan. Seriously, we wasted hours when this book came in before we realized we had to make it available to you all too!
