There are 3 books in this series by Gordan Korman, and each individual book is not very long, especially compared to books like Restart and Unplugged, also by Gordan Korman.
These books were fun to read, and there were quite a few funny moments. There were also plenty of action and intense moments in these books, and I did like reading these books. I have to give this series an age rating of 10+, because there is violence and death in this series. I have to rate this series 4 Stars, because they aren't very special or unique, and there isn’t really any interest in reading these books again.
I can, with a bit of hesitation, recommend this series to read, and I can definitely see some people really enjoying these books. In the end, this series is just not really for me to read several times, and I can see people who outright don’t like this series.
