I just turned my girlfriend onto this series. She usually sticks to straight lit stuff but she is hooked 100 pages into book 1.
I'm reading Dancing with Dragons. Unlike cara, I find the descriptions and new areas and minutiae and morbid obsession with the cruelties of this world and lack of sexual political correctness as fascinating as ever. I like Martin because he has such a steady hand on the rudder. He rarely shifts tone, which in series this huge is saying a lot. I think he did mean it to be three volumes but, knowing his old, now deceased, agent, probably got pressured into, as
@islode said, hamming it up. I think of everything after book 3 like an expansion on a video game... same world, just new missions. Still, he is heading somewhere if he lives long enough to get there.
