...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.
Short, but sweet. The pacing was nice, the characterization wasn't bad, there were characters who seemed to know more than they rightly should, but I'm willing to write that off since it's a short and we don't know the backstory and for all we know, those characters have suspected for ages.
