The book (McCaffrey) and the reading (Hill) were both first class. My only minor criticism is the "Irish" accent that some of the characters have. I get that these characters have Irish ancestors, but I had trouble understanding some of the words, and by the end of the book I was frustrated/unhappy about it. This in no way detracts from my total enjoyment of the Pern series (I've listened to 5 or 6 of them and plan to continue).
As a Huge science fiction fan, I was excited to start this series. Since this book is the first in the series, chronologically, I thought I'd give it a shot. It was acceptable and I think I might listen to others. The narrator had a nice voice, even though he couldn't properly speak with any accent that wasn't American. It's not as good as Tolkien, or the Dune series, but its good enough to pass the time.
