Based on my knowledge of the second book, I'd expect the first episode of season 2 to involve more setup and exposition than were in the final episodes of season 1, but not as much as in the first episode of season 1.
And there are no main characters. Never forget that.
Here is a spoiler, everyone dies. GRRM is a one trick pony.
Oh, come on.
3,000 pages maybe, but not 7,000 - that would be 7 books, not 2.
Also, there are main characters. Daenerys and Jon Snow will be there till the end, for instance (especially since they might be half-siblings - POSSIBLE SPOILER ALERT!).
i read where the show producer said he’s not going 100% by the books. the same basic storyline and all but some differences, some things out of order, etc... so the tv show won’t just be a carbon copy of the books
