I had this book on audio as a child and very much enjoyed re-listening to it after ten years. It's a good story, very exciting and full of adventure. The narrator is superb. Would recommend this to kids aged over about 8-9 and adults as well.
I listened to this after seeing the first film and got hooked! It's really gripping and exciting. As soon as it finished I had to buy the other two books as well. One slight problem was that I didn't really like the narrator's style so I bought the others as paperbacks.
I remember this book fondly from my youth, and the narration does the book justice. Strongly recommended to anyone with a taste for the Tolkein-esque! I just wish the BBC radio play was also available.
