my dad gave me this to read around 2011-2015 when i was a kid, he likes books like enders game and hitchhikers guide. i remember thinking it was kind of sexist and it was a series of books. i remember a scene when he's being coronated as king and very few of the people in the far off land came to see. would really any help or guesses to find this book

What is the man's job in the modern world? What was he doing when he's transported to the fantasy world?
