Game of Thrones and the sequels

I started watching the Game of Thrones on HBO.  It was ok.  The books are better but he really likes moving from character to character and the themes are very confused.  Some characters are interesting and others not so much.  There is sex but it is not like in HBO and very much secondary to the contending groups for leading.  All this is in a very creative world.  It is like nothing I have read and is a good way to spend a summer reading.  I am in the third book A Storm of Swords and it will take me the rest of May!
