Query: Harry Potter 3

This is a great book and it is the best of all the books so far! It is a really great series to read and it is so creative and imaginitive. I recomend it for ages 9-13. It is great for all ages and even adults are starting to get into it. Harry Potter loves the wizarding school that he goes to called Hogwarts. The only thing is that every year something terrible happens. All the books are very exciting and enjoyable. Please read them!
