Bought the book yesterday at Target;
began reading at 3:40 pm;
finished at 8:15 pm!
To be honest, I was slightly disappointed, but it's not like I regret reading the book or anything. What I find fascinating about book series (serieses? how does one pluralize that?) is how you get sucked into the world that the author has created, to the extent that you're willing to read dross just to see what happens next. Which is not meant to suggest that Book 6 qualifies as dross; the best examples I can give here are various sci-fi/fantasy series, like the David and Leigh Eddings books, the Xanth books (both of which I gave up on years ago), and Anne McCaffrey's Pern books (which I will still read, but refuse to spend money on any more, and really, I can't bring myself to read the ones her son has been involved with either). I guess sci-fi fantasy is especially prone to this because this is a genre in which the authors most explicitly create new and different worlds, but I suppose in another sense you could apply this even to something like Danielle Steel (because I refuse to believe that the world she describes in her books bears any resemblance to reality).
Oh, and this isn't very surprising, but in case anyone wanted to know:
(I'm way too chicken to be in Gryffindor!)
