I liked it, but I already liked the TV series, so I knew what to expect. Now I can compare!

Things I liked better in the book: There is no omnipotent, omniscient being as in the series. Everyone just knows what they see and hear about, and works with mundane methods. Also, Luis, Ashton and Eli are amazing extra characters! Also, yes, Simon is definitely a channer.

Things I liked better in the TV series: How the entire situation came to happen. Jake's role, Simon's, and most of all, Janae's! Also, the entire ending. That version is just way more satisfying.
