Cassandra Clare - Clockwork Angel
This looks interesting. It's the first book in a prequel trilogy. The library does not seem to have any of the original trilogy (Mortal Instruments). Could be steam punk. Could just be neo-Victorian. I'm not sure - it's got paranormal stuff, it's set in Victorian London, it's YA. I'll let you know.
Other thoughts - we approach Christmas, and there are some books that I tend to read right around Christmas - The Shepherd
