Harry Potter and the Half-Blood Prince (Book 6)

Harry Potter and the Half-Blood Prince - J.K. Rowling, Mary GrandPré I LOVED this book. I bought it as soon as it came out and read it all in one day/night. Luckily I didn't have to work the next day. I was soo upset that Dumbledore died. But like most people I knew there had to be a reason why Snape killed him. I just couldn't accept that Snape was a traitor.
