[SPOILER]
I was pretty frustrated by this book. I did not find any personality portrayed in this book to be very realistic except for our yuppy-ish protagonist 'Moby'. I did not find several details to be very realistic, most pointedly the extent the cops went to protect Sarah Byrnes after Moby was stabbed.
Also bothersome, only two types of Christians were showcased in this book: Opinionated, offensive liars, and universalist 'God is what you want Him to be' people.
Really the whole book annoyed me. The only thing that I liked was the use of an overweight protagonist and an un-pretty supportive character.
