Shepherd Book's backstory, finally told through this graphic novel. For fans of 'Firefly', that's really all you need to know.It's a must read for Firefly fans, but it also left me feeling oddly unsatisfied. Perhaps that's simply because I'd have loved so much to have this story unfold through the TV series, as it should have been. Also, Book's story turned out to be not what I had expected, and I think I was a little disappointed by that.All that said, however, it's a very good backstory, and it seemed to me to fit in just fine with what we know of Book from the TV series and film. If you want to learn the answers to the mystery of who Book was before he was a Shepherd, and you're not diametrically opposed to reading 'comics', then you should read this.
