Spy School: Revolution, by Stuart Gibbs, follows the story of a spy in training named Ben Ripely. When the CIA is discussing with his parents about placing them in the witness protection program, the most skilled spy in training and a close friend of Ben’s named Erica Hale launches an attack on the CIA. As the CIA hunts Erica, Ben realizes that Erica must have been blackmailed. Ben must go rogue to find out the organization that’s secretly pulling the strings and bring them to justice. I really liked this book, but I don’t think it was as good as its prequels. The ending did not make any sense to me, but I think this book had an interesting villain and was a fun read. I would recommend this book for middle schoolers and high schoolers but mainly middle schoolers.
