City of Bones (Mortal Intruments #1)

When Clary Fray heads out to the Pandemonium Club in New York City, she hardly expects to witness a murder—much less a murder committed by three people covered with strange tattoos and brandishing bizarre weapons. And she’s more than a little startled when the body disappears into thin air. Soon Clary is introduced to the world of the Shadowhunters, a secret cadre of warriors dedicated to driving demons out of our world and back to their own.
