Sometimes good, sometimes so so. It is a marathon listen in the audio books. Some of the books are around 40 hrs long. My problem is that the main protagonist is unlikeable... petulant, bad tempered, childish, . The battle scenes start to get repetitive and boring. I start getting restless listening to them. For the most part the writing is good but the characters tend to get a little flat. As far as the audio books the narrator's are outstanding and I like that they used the same narrators through the whole series.
