From what I understand, there is an unabridged version being released eventually. I heard it should be coming out towards the end of the year, but there is probably someone here that is more in the know than I am.
I also read the Kindle "enhanced" version a week or so ago and was pretty disappointed with it... it had some interesting bits, but it seemed like it could have been much more fleshed out. I had NO IDEA that I was reading an abridged version until just now finding this topic. There's absolutely no mention of this on Amazon (from the author, publisher, nobody), and now I feel severely cheated. I would have gladly bought the hardcover instead if I'd known I'd be getting the full story -- you know, the actual story that OSC wrote that I thought I was buying, not something a third of the size that somebody else edited down. No wonder it felt more sparse than I expected, since it was missing a lot of the story. I contacted Amazon about this, and they said unfortunately it's the publisher's doing, they choose to advertise that it's the same as the print version and haven't edited the product information to explain that it's not really the same content. Pretty deceptive on the publisher's part..
