There have already been many good reviews written about this book, some praising and some condemning.
I myself loved the book and the way it is narrated by the different characters. Is it weird that my favorite character is Tyrion?
The story is about a kingdom in turmoil for the throne (thus the title) and the many high families involved, including the exiled children of the previous king. Add to that the Black Guard that stands guard at the huge ice wall protecting the kingdom from the Others. The ending of this book was a surprise to me. I can't wait to see what Dany will do!
This book leaves a lot of unanswered questions which leads in to the rest of the series which I will most definitely read. I just hope the last book does indeed bring everything to a close.
One note of warning. This book describes human savagery and butchery at it's worst with beheadings and war, descriptions of rape and debasement of women and the "lowborn". If you are sensitive to that sort of thing then this book may not be for you.
