Query: It's pretty good

I am a big fan of Harry Potter and I read books #1-6. I found that in books # 5 & 6, J K Rowling lost a few of her amazing ideas because they seemed to get boring. In book 6, she did do a better job than in book 5 and it is also not as long and boring. There is great suspense and delivery and it will keep you reading.I recommend this book for any Harry Potter fan.
