I started reading this book before I learned it was coming out as a movie. Where do I live? In books I guess. 
 We begin book 1 with Clarisse Fray, a fifteen year old girl going to a night club with her best friend Simon. There she sees things she shouldn't be able too. She sees three teenagers killing another teenager, but then he disappears. She meets Jace Wayland who tells her the truth. He is a Shadowhunter. 
 Her world turns around when she discovers that she may not be a "mundane" because she has the "sight" and is able to see the Shadowhunters. They are part angel, part human. They are in this world to get rid of demons. Yes, this world also has vampires and werewolves, but the Shadowhunters are the main theme. 
 There are 3 immortal instruments. One is cup that can make a human into a Shadowhunter. There is evil in the name of Valentine Morgenstern who wants to get the cup and also kidnaps Clarys mother. 
 Is up to Clary to find the cup and stop evil from harming humans and things that go bump in the night. 
 Plenty of action. The interaction between Jace and Clary is intense. 
 The world building was well done. I'm glad I read it. Now, I want to see the movie.
