The city of bones is the first book of The Mortal Instruments series.
Here’s a summary:
City of Bones begins with a sixteen-year old girl named Clary Fray, who lives in New York with her mother, an artist. She comes home one night to find her apartment ransacked, her mother gone — and a slavering demon ready to tear off her head. Once the demon’s dealt with, Clary follows the clues to her mother’s disappearance into an alternate New York filled with hideous demons, hard-partying warlocks, not-what-they-seem vampires, an army of werewolves and the scariest thing of all: the secrets of her mother’s past.
A thousand years ago, the Angel Raziel mixed his blood with the blood of men and created the race of the Nephilim. Human-angel hybrids, they walk among us, unseen but ever-present, our invisible protectors.
