Query: Harry Potter and the Half Blood Prince

I read this book because of an English assignment I had to complete. This book was suprisingly good. J.K. Rowling is an incredible author. She writes so well! The 6th Harry Potter is packed full of surprises and different twists that will blow you away.Harry is changing so much in this book and is on his way to adulthood. The adventures in this book that Harry experiences and go through are not like any other that he has experienced. To tell the truth I really enjoyed this book. I would recommend it to anyone that has enjoyed the past five books.
