"huh?"
first, the quality of the book is excellent. It's very complicated, though, and I found having my husband with me (who had read the book previously) to explain things was helpful.
second, the dramatized voices were excellent. Scott Brick is my absolute favorite reader, and I was very pleased with his work as well as most of the others.
My complaint is that the dramatized voice actors were only in about 1/4 to 1/3 of the reading. The rest was read by the narrator. I'm used to this format (a single reader) for audiobooks and it normally wouldn't bother me, but it was VERY annoying to be "teased" with the actors only to be let down with the narrator's lame accents through the majority of the story.
