A new trailer has been released for the adaptation of the young adult novel, The Mortal Instruments: City of Bones.  Set in modern-day NYC, the film tells the story of Clary Fray (Lily Collins), a seemingly ordinary teenager who discovers that she is the descendant of a line of Shadowhunters, a secret organization of young half-angel warriors in an ancient battle to protect our world from demons.  I have no familiarity with the source material, so I'm more interested to know how fans are responding to this adaptation.  From an outsider's perspective, I'm fairly indifferent since nothing in this trailer or the previous one has really grabbed at me.

Hit the jump to check out the trailer.  The film also stars Lena Headey, Robert Sheehan, Jamie Campbell Bower, Jonathan Rhys Meyers, Kevin Zegers, Kevin Durand, Jared Harris, and CCH PounderThe Mortal Instruments: City of Bones opens on August 21st.
