Well there's going to be 7 books altogether, he has 5 written but two of them are split into 2 because they're so big (so technically there's 7 books written already lol). I don't think the 6th book will be out till next year or the year after
Well, Season 1 followed the book pretty spot on. 2 and 3 changed things a little bit but it's still following the story at more or less the same pace, although i think Book 3 is being spread out over seasons 3 and 4.
Yeah, it was very good, no episode next week but the last two are going to be amazing. How are you getting on with, are you getting to grips with the characters a bit more?
