Well, reading the book is a must for a fan. Without the book you don't know all the details. And then you also have to read it more times. I've read it 2 times, but when somebody asks me a question and I know the book provides the answer I can't remember. So maybe, to fully (as good as you can) understand GF you may have to read it many many times. Wondering how many times Turnbull read it. He knows almost everything about GF. Oh, I just read 250 times. Well guys, if you want to be as good as him/her (I don't actually know what he is, guess him) you first have to beat him at this point, then you might have a chance.
