There is one book that is considered the bible and almost mandatory reading for pilots: Stick n Rudder. Never before or since has there been a better book to learn about flying and it is as relevant to a sim pilot as it is to a real world 747 captain.
Stick and Rudder: An Explanation of the Art of Flying By Wolfgang Langewiesche | Used | 9780070362406 | World of Books
It's not hard to read at all, it is very human. I highly recommend this to you.
