Clockwork Angel

Clockwork Angel: The Infernal Devices, Book 1 by Cassandra Clare

I stumbled on this as I was searching for Clockwork Angels based on the Rush album. This one doesn't have any music tie in. Instead it is your typical young adult fare. Here we have demon hunters. The world is a somewhat "normal" world on the surface. However, there are also vampires, werewolves and others. One girl thinks she comes from a normal family. However, she has the ability to "shape shift" to appear identical to others. She joins up with a group to find her brother (and help the world.) She also discovers that her family was not as normal as she thought.

Then things take a turn for the weird. There is some subterfuge on the part of the bad guys. Her brother ends up being on the bad side. There are some big battles and some narrow escapes. All is pretty typical for the genre.
