Twelve hours after I started it, I finished it. It was worth every hour, every minute, indeed every second. I finally went to bed at 3:30 am. The next morning I re-read the last two chapters to answer a couple of nagging questions. I'm anxious for everyone else to finish it so we can talk about it. I know Cherlyn's already reading it again, as am I.
My take on it? I thoroughly enjoyed it. You'll get no hints from me as to the books' innards.
