This was short yet very interesting. I enjoyed all the notes that Harry, Ron, and Hermione wrote in the book. They were a great reference to events in the serise and made me laugh and smile. It is a good idea to read the serise before you read this book. It will Mae some thing clearer and avoid some minor spoilers. I wish muggle textbooks were as interesting as this. I loved how much depth it gave to the windsurfing world for such a small, short book.
