This is one of those rare books where I think it's going to be better as a movie. The writing style is so spare, it's almost like reading a movie script or a novelization of an already-existing movie. 
 It isn't a bad thing - I really enjoyed the majority of this reading experience. It was thought-provoking, entertaining, and creative. I couldn't wait to find out what happened! 
 (view spoiler)[My only complaint is that the multiple Jasons thing in the last act of the book was just so silly at first, it pretty much negated any emotional investment I'd accumulated. I get that it was probably required based on the "rules" of the book's physics, but I had trouble taking it seriously. Especially the Jasons chatroom. It's another aspect of the book that I think will come across better on a movie screen than it did as described on the page by this author. (hide spoiler)] 
 I'd definitely recommend this, especially as a quick-moving weekend or vacation read. This has also been a bad month for me in terms of reading choices, so I feel especially generous towards a book that successfully engaged me. Thanks, Dark Matter!
