Ideal for: 6th-9th graders
Rating: 9/10
This is a great book, and the latest installment in Stuart Gibbs Spy School series. It doesn't disappoint. I am a huge fan of this author and his other series such as the Moon Base Alpha series and his Funjungle series. It has all the action and the humor that the first four did. I would definitely recommend it.
