...this confuses me. So...it's like tumblr...for books?
Either way, I'm mainly on Goodreads. I do occasionally come here, and also do periodically import my shelves from GR here, but GR is a more sure bet for contacting me.
The problem with this book is it doesn't really stand on its own. It requires that you've read the previous book(s). I also feel like the characters didn't quite come into their own either. They're not bad, I guess, but we're told a lot of stuff and it doesn't feel like much of it really meant much of anything.
