Like the first book of the series I read this book on a Kindle and listened to it on an iPhone switching back and forth as needed.
Wow, these books are long. It took me a few weeks to make it through this one. But it was a great ride.
The story goes on and on with no end in sight. The characters are holding my attention and I look forward to reading the third book, although that will have to wait until June or so as I am in non-fiction book mode now.
I am still surprised by how much I am enjoying these books, especially given their length and relatively slow pace. I was able to sum up most of the various plot lines from the book to my wife in less than an hour, I left out some of the good bits so she will still have some surprises left when we watch the TV show.
From Wikipedia (http://en.wikipedia.org/wiki/A_Clash_of_Kings):
A Clash of Kings picks up where A Game of Thrones ended. The Seven Kingdoms of Westeros are plagued by civil war, while the Night’s Watch mounts a reconnaissance force north of the Wall to investigate the mysterious people, known as wildlings, who live there. Meanwhile, in the distant east, Daenerys Targaryen continues her quest to return to and conquer the Seven Kingdoms. All signs are foreshadowing the terrible disaster that is to come.
I rate this book a 9 out of 10, it is even better then the first book.
