It would be good if the mods (or submitter) could change the title to reflect this, I think that a few people might be upvoting before they actually try to download the book and realise that it's not the full version.
I know it's narrow minded, but I was bummed that I had paid full price for the epub. Making a couple of chapters available for free is a great way to promote a good book, let the material talk for itself!
