Query: Only if you have to...

I love all things Harry Potter except this book. It is not produced with any of the Harry Potter/JK Rowling permissions & I actually returned it! It is not worth it. It is a dictionary of things like: ghost - throughout history people die and sometimes remain behind in the form of an aparition... I made this up - but that is all this is! If you have to have all things Harry Potter, get it used.
