Harry Potter and the Half-Blood Prince
Decided to read my first ever Harry Potter book, having seen every film thus far. Given the Half Blood Prince movie is due out in July, the book of the same name was the obvious choice. And I loved it.
Even though it weighs in at 600+ pages, JKR writes so well that you hardly notice the length. As Harry gets older, so does his audience, so the tone of the book is very dark. The final trailer for the movie came out just as I finished and it too is dark.
