This is a rare and unique copy of the Harry Potter book "Harry Potter and the Half Blood Prince" by J.K. Rowling. The book is a very early first edition and has a misprint on page 99 where there are 11 owls instead of 10. It is a hardback book and would make a great addition to any book collection. The book has been well-preserved and is in excellent condition for its age. It is a must-have for any Harry Potter fan or book collector.
