I own all of them and am slowly reading them. I'm still on the first one (I've never seen the show because I don't have HBO) and I have to say that so far there isn't much that I find interesting. I find the writing to be quite dense. Honestly I read it when I'm trying to fall asleep but I can't because after one chapter I fall asleep haha. I really wanna get into it because it's so popular and I wanna be able to talk about it with other people, but it's just so dense.
