I just finished and had to surf for a synopsis since I don't think I understand the end. Was it real or not? Part of me wants to use a short line by Crosetti (describing the movie life) - "keep 'em guessing at the end" or something like that - to explain that we will never know. I agree with others that the inordinate sex life of Jake was too much (even though sex addiction is a popular theme). The ridiculously successful outcome of his dysfunctional siblings - as well as Jake being a former Olympian - was over the top at first, but as I pressed on, I really liked the characters. Especially Paul and later on his evil but sage father. The sex addiction of Jake was mirrored by the greed addiction of his father. Smart book. Really liked it but limited audience with whom to recommend. Will keep Gruber on my radar.
