Will they have to close Hogwarts for good? Will Harry have to face the evil Lord Voldemort and his Death Eaters? What is Malfoy up too?

          This book was really good because of all the unexpected twists. It held my attention the whole book. It makes you feel that you want it to keep going on. I did find one thing wrong about the book though. I saw some grammar errors and even a wrong name.  In this book the romance heats up quite a bit since everyone is getting older.  Out of all the books I'd say that this was my favorite out of the 6 because it wasn't super long but it was long enough. I like how J.K. Rowling does cliff hangers to keep people reading. I like how she sets everything up and how a lot of things from other books foreshadow onto all of the other books. It is certainly worth reading in my opinion because after you read it once, you want to read it over and over again. This book would be better for teens and adults because there are some scary parts, mainly at the end, but I think children who can read this level would love it. I give this book a full 5 stars!
