Favorite book - Harry Potter and the Half-blood Prince. The story had a noticeably unusual air and feel to it; was also written differently than the other books. All the characters had developed really well and I guess, the underlying misleading plot of the story made it a very fascinating read, along with the interesting elements such as the Horcruxes, the Potions textbook and Voldemort's past. Let's not talk about that shaky terrifying ending! I might have shed a tear or two...or for the whole day. It was my best reading experience of all the Harry Potter books!
Favorite movie - Deathly Hallows part II.
