Harry Potter and the Half-Blood Prince

I just got my copy in today's mail. Irene had pre-ordered it for me from amazon.com as a Father's Day present. (Nice wife!) Now I have to figure out when I'm going to read it - I stalled out partway through Order of the Phoenix, when Harry was being very much a stupid teenager, and the adults weren't helping any. Maybe I'll go back and try to finish OotP now...
