Two of my friends were raving about the audio books of Harry Potter and since I have been wanting to re-read the series for some time now, I decided to get the audios. They are absolutely fantastic! I read the books so quickly years and years ago (because how could you not devour them), and there are small details that I had forgotten. I love that I can experience them again in this different way (after reading and seeing all the movies). The narrative is Jim Dale and he keeps you so engrossed with the subtle changes of his voice for the characters.
I decided to use this one for the werewolves square because of the prevalence of Professor Remus Lupin in this book as the new Dark Arts teacher.
