I'm a fan of the books--the last one is not out until the 21st at Midnight.
So why does an adult enjoy these books aimed at kids???
When I was a camp counselor about 6 years ago, my campers were calling eachother muggles. I wasn't sure if it was a new curse word, so I asked them what it meant and where they heard it. They told me it meant non-magical people, and it was from Harry Potter. They started using more of the Wizarding jargon in their everyday speech, so I felt the need to read the first book that week just to understand my campers. My mom had it, as she's a teacher, so I borrowed it, and found that my inner child enjoyed the book almost as much as my outer adult found it well written. As the other books were released, I watched my campers who, the summer before, had trouble reading, come into camp beaming with pride at having read a 400some page book, or a 700some page book...
No matter what your views on the books, the subject of magic and witchcraft, or just the hoopla surrounding the books release, you cannot deny that anything that gets kids to read, and makes them excited to read, has some serious merit.
Kudos to JK Rowling, who I believe is brilliant.
I can't wait to read the final installment!
