The book is amazing (of course), but some of the voices the narrator used are almost unbearable. Varys especially, he sounded like how a deaf guy sounds when he talks. Tyrion sounded like a leprechaun. BUT, the narration becomes a lot more enjoyable if you change the speed to 1.25x
The book is great. I love the depth of the characters but I love Roy Dotrice's portrayal. He does any incredible job bringing these characters alive. I hope he is able to read winds of winter!
The Song of Ice and Fire has a capable bard at the helm, and Dotrice captures the spirit of the tale so brilliantly that I am tempted to go through the series with audio alone. So far Whispersync has served me surprisingly well, though. A successful coup all around, as far as I'm concerned.
