Oh my fucking head... that is definitely my new favourite book of the series. PoA has been de-throned. I finished reading it almost nine hours ago, and have been absorbing and processing it ever since. I'm taking the time tonight to post my reaction to one of the final chapters... the one which seems to have the most people's trousers in a twist... and the one which has me the most excited.
Note: The following is an over-enthusiastic ramble, thick with spoilers, and dripping with speculation. Enter at your own risk!
