The Mortal Instruments City of Bones (Book 1)

1) Clary is 15 years old and she met the Shadowhunters. I think that Clary and her mother are also like them since they can see them and demons are interested in them.

2) Jace is one of them. Demons want to kill her, maybe.

3) Clary lives in New York City. Clary will join with the Shadowhunters to kill of demons.
