What do you think? It had things which people were expecting (Tessa and her Clockwork Angel), but fans are already trying to pick clues out of the cover. What's the book Tessa's holding? Why is it glowing? Why isn't she wearing any rings (if you read Clockwork Prince, you understand...)? What has Saint Paul have to do with it? WHAT WHAT WHAT?
I really like it. I don't love it, but I sense I will warm to it more when I get my hands on an actual copy in March 2013 (I love Clockwork Prince so this has to be EPIC!) And as I haven't read the fourth or fifth books in the Mortal Instruments Saga, this is my next Cassandra Clare read! Can NOT wait!
Oh, while I remember: Earlier in the week, Cassandra Clare revealed the teaser poster for the movie adaptation of City of Bones.
