I'd call it by another Title, but who cares? I finished the book today. It is a fun read. Action, a good paced plot (save possibly the first few chapters), interesting characters, and a very well done finish. This is the only HP I've read. I may read some others even thought I already know the end of the saga, just because I like how the author (J.K. Rowling) represents her alternative universe. As a Christian I believe in such a reality, although not this specific one. Probably my view would be closer (only closer, not exactly) to say Frank Peretti's unseen universe in his novels.
Anyhow, I liked the book. Get it, it's on sale at like 50% off everywhere. You don't even have to wait for the paperback at that price, and have a fun read!
