I'm looking for a story I read when I was younger that was of the style where it is in first person, with the main character recounting it and saying it's a true story. It was set in the modern world, where there was a conspiracy of people that I think had something to do with librarians or the illuminati. They that had convinced the normal world that new weapons like guns were worse than old ones like swords, and also hid the fact that there was another continent in the middle of the pacific, although I think the second thing was mostly mentioned as an aside. The main character is recruited by the opposition, who also uses old stuff, although I think one of them uses guns but calls it archaic tech. I think it was somewhat magic related, and I remember there were glasses that had some sort of laser effect
I think it was children's fiction, and also at the end I remember there were reading comprehension questions
