The characters were the kind that I could really get attached to. Yes, there was some apprehension in the beginning with the whole 7 kingdoms and 7 kings that were a bit overwhelming and once I got passed Katsa being the whole "I am woman hear me roar" thing I truly loved her.
All in all: It is a well written, well paced book. It wasn't hard to picture the surroundings nor the characters.
Read this book.
