The movie trailer for “The Mortal Instruments” has arrived and feels a little like twilight the next generation.

Mortal Instruments revolves around Clary Fray (Lily Collins, Mirror Mirror), an ordinary teenager living in modern New York City, who discovers the truth about her lineage after her mother (Lena Headey, Game of Thrones) mysteriously vanishes: namely, that she is a descendant of the Shadowhunters, a legion of half-angel warriors who (in secret) protect humanity from the forces of darkness. Soon thereafter, young Clary begins her training as a demon-destroyer, with assistance from Hodge Starkweather (Jared Harris, Mad Men) – who is the elder caretaker at the Shadowhunter Institute – and the handsome-but-deadly warrior Jace Wayland (Jamie Cambell Bower, Camelot).

The Mortal Instruments: City of Bones hits theaters August 23, 2013.
