When I first found this book, a parody, I thought it had to be fun, as my sister and I like to make fun of some certain scenes in the Harry Potter books and movies ourselves. For example the scene where Ron is under some love spell in HP6. And I do like to read a parody, as long as it's done properly, and funny and with some respect to the original. (I do really like the musicals Starkid has made about Harry Potter)
But, I was really disappointed. There were a lot 'jokes' in it that just weren't funny, and there was no story in it at all. I actually liked the first few pages the best, in which is explained that it has nothing to do with JK Rowling. It took me quite some time to finish the book, as I was not interested at all in what was going to happen next. Perhaps I should have read the first books before reading this one, but I don't think I will go and find out.
Don't give it a try, it's awful.
