I'm finally getting around to "reading" the HP series (I've purchased the first two audiobooks narrated by Jim Dale), since I've already seen all of the movies and I was told by my coworkers I should be fired for not reading them. Hah! :) Great introduction to the series. I loved listening to Jim Dale for this. He read all of the characters very well.
Of course I already knew what was going to happen, the style of writing didn't surprise me. All in all a very good YA book. A little less advanced than what I'd prefer, obviously, but I can appreciate it for what it is!
