Well, they aren't exactly Game of Thrones books, they are A Song of Ice and Fire series. ASOIAF for short version. But it seems that GoT caught better and the TV show has more fans, so I will be focusing on the relation between two.
There are five books in the series so far, and two more to come soon. I just hope that RR Martin lives long enough to write the end. At the tempo he is going, he will be around 120 when he's done.
I plan to start by review of first 5 books and then focus on some details in the books. If you want me to focus on anything in particular, just let me know in the comments.
