no - there are plotlines and characters from book 1 and 2 that aren't in the show.
The first two books are pretty quick reads, at least they were for me.
I'm going to read them again since I plowed through them too quickly the first time since I wanted to know what happens.
I finally finished A Dance with Dragons last weekend. Wow wow wow. Mr Martin does NOT fuck around when it comes to killing off major characters.
I hardly remember who he killed off in that book.
I "powered" through all those books in about a year, maybe less. I read, I read a LOT and have been since 3rd grade. But for some reason...those books got a little much for me. I love them and still consider the first book to be in my top ten books...but I don't even start to argue with those that hate the series.
