Have you read the book Spy School yet by Stuart Gibbs? I have just started it and I can't put it down. Imagine you find out that, without your even knowing, you have been tapped to become a spy for the CIA. You have to tell your friends and family that you are heading to Washington DC to go to a special science school, but in fact you are training to become an secret agent. It isn't quite as glamorous as twelve-year-old Ben imagines it might be and for some reason his classmates seem to believe that he is more talented in computer coding and hacking than he really is. You will be on the edge of your seat trying to figure out what is really going on at Spy School. Great choice for 5th grade and up.
