Maybe it was because my expectations were so high, but this book was a disappointment. I got it as an audio book to listen to on the treadmill and sometimes turned it off before my workout was over.
Because of the review I heard on NPR, I was expecting a dark comedy, but there really wasn't any humor of any kind that I could detect. Being an audio book, the lack of humor could have been due to the tone of the narrator.(But since I've even managed to enjoy books read by Dick Estell, I don't think that is the case.)
Perrota presented some interesting scenarios, but I felt like he couldn't decide whether this was a serious examination or a satire of human reaction to an inexplicable catastrophic event. A friend had an interesting observation which I agree with - "They thought the selection was random, but it was actually all the boring people who were left behind."
