This book is by far more exciting and a joy to read than is predecessor. There are times you will cheer and there will be times you'll scream "Why did you just write that George R.R. Martin, GRRRRAAAAHHHHH!". This is one of those books that will shock you and also make you feel glad to be alive (to read). And if you think this book is good, wait till you read the next one.
