Today is the official publication date for The Clockwork Angel, the first in the Infernal Devices series by Cassandra Clare (author of the Mortal Instruments series), and here is the official book trailer:

I wonder about book trailers and whether they’re a good idea – do you want to see what the characters and landscapes look like in a book trailer before reading? Hm.

If you haven’t reserved it yet and you’re interested in reading it you can do it now!
