I teach school and most kids from 4th grade and up through beginning of high school love these books. They are high adventure with fun characters. I like that there is a whole series of them so once they get introduced to the series there are many books for them to read. They are historically accurate and so they are learning about historic events in a fun way. There are also life lessons learned by the characters. We read one a year with my class and they look forward to it. I helped at a daycare during Covid while the schools were all shut down. One on the boys considered himself above all this school stuff and didn't want anything to do with me or my reading class until I told them we were reading a novel together and one of the choices was an "I survived" book. Immediately he wanted that one and the majority of the kids did too. They no longer were fighting me about reading, but excited for me to come and read with them. Great Books!!!
