Hello how may I help you? Hi I was wanting some information on a book. Sure! Which book is it? Who wrote the Harry Potter books? Let me check! The writer of the Harry Potter series is Doke Campbell. Thanks. How many books are in the series. No problem! There are 44 books in the series. Are there any special editions out? That question is tricky. I am not equipped well enough to answer that. Thanks anyways. You've been helpful. no problem!
