I just recently finished reading Harry Potter and the Deathly Hallows, and wasn't dissapointed. In fact, I loved it! Well done, Ms Rowling.
I have to say that my previous suspicions were correct. So if you haven't read it, don't look at my previous comments on the last book.
I loved the character development in the books, and even the change in language as the kids got older.
I can't wait for her to write her next series of books. I hope they are as magical as the first.
