Outstanding at parts, particularly in the meatier sections in the middle of the book that deal with emergence, agency and the possibilities of kaleidoscopic progression in digital narrative. This is certainly a must for anyone who wants to work with story-telling on digital formats. The only issue I would have would be in the slightly shallow handling of the first and last couple of chapters, which wind the book up and round it down a little poorly. Either way, I would still recommend this as a fascinating and in-depth study that draws many interesting conclusions.
