Exclusive: New Image from THE MORTAL INSTRUMENTS: CITY OF BONES Featuring Jemima West as Isabelle

One of the more anticipated Young Adult adaptations coming up is director Harald Zwart’s take on The Mortal Instruments: City of Bones, and Screen Gems has provided us with an exclusive first look at Jemima West as the character Isabelle in the film.  The story follows Clary Fray (Lily Collins), a teenage girl who discovers that she’s descended from a sect of half-angel warriors who protect the world from demons.  The trailer promises some rather intense fighting sequences as well as plenty of supernatural sorcery, so hopefully fans are happy with the book-to-screen adaptation.

Hit the jump to check out the new image.  The film also stars Jamie Campbell Bower, Jonathan Rhys Meyers, Lena Headey, Kevin Durand, CCH Pounder, and Kevin Zegers.  The Mortal Instruments: City of Bones opens on August 23rd.
