My 9 yo son and I have recently discovered David Walliams, and we've very quickly become huge fans. Demon Dentist is the most far-fetched (of a fairly far-fetched set), and we loved it. My son laughed hysterically at many points throughout the story, and frequently imitates the humor and voices himself. David Walliams' performance is first-rate with wonderful voices for all the characters. He's done a marvelous job creating thoughtful and thoroughly entertaining stories for children (of all ages).
