I don't have a book to recommend but I have a tip. The movie record button can be re-programmed to set the ISO and other functions. I don't shoot video with my D750 so I re-programmed mine. If your daughter doesn't shoot video, she may want to re-program it. Nikon has an ISO button behind the shutter button in their latest cameras. It's convenient to have it there because ISO is something that gets changed a lot.
