Have You Read It? Rate "Harry Potter and the Half-Blood Prince"

Happily, I was able to buy a copy of "Harry Potter and the Half-Blood Prince" despite having neglected to preorder it. While I haven't finished it yet, I have already heard from some people who have completed the book. When you finish it, let me know how you rate JK Rowling's newest book by voting in my "Harry Potter and the Half-Blood Prince" poll and giving it one to four stars.
