This is an action-packed, can’t put it down book for all ages. My students are hooked to this high adventure series. I broke down and bought the entire series for the class. Girls and boys both love it. The setting is in England following an orphaned boy who has been raised by his uncle. In one day, his life changes from an ordinary 14 year school boy to a high energy spy. However, use caution as the espionage theme carries much violence.
