In my opinion, this was a good book for kids ages 11-15. It was a little difficult to get into, but once you do, you can't put it down. I liked how it was semi-humorous, and it had a strong ending. I dislike books that leave the reader hanging. Keep in mind that there is some adult language used as well as a tremendous amount of deaths. This book was okay, but definitely not one of my favorites. I would read the first book, Alien Invasion and Other Inconveniences before reading this one.
