I think this is a case of a book and a reader being a mismatch. The Incrementalists is interesting, fast-paced, often mind-boggling -- but ultimately, not for me. Based on the synopsisI think I expected something more along the lines of a paranormal thriller. Instead, I discovered that this book is about virtual worlds, abstract constructs, and non-material existence via shared memories. Honestly, a lot of it went over my head. I liked a lot about this book -- interesting set-up, great characters, lots of food for thought -- but I had a problem following the actual plot and understanding what had happened, and that took away from my enjoyment. 
 I think for people who are more into these type of concepts than I am, it's probably a very, very good book.
