Harry Potter and the Half-Blood Prince

When Harry's summer is interrupted by Professor Dumbledore himself visiting the Dursleys and taking Harry to help recruit the new Hogwarts professor, you know this is going to be a weird one. This school year is promising private lessons with Dumbledore, Snape as Defense Against the Dark Arts professor, and Harry suddenly becoming a top potions student (thanks to a textbook previously owned by one Half-Blood Prince), so it's sure to be a wild ride.
