Screen Gems has teamed with Constantin Film and Unique Features to develop the motion picture franchise Mortal Instruments based on The New York Times Bestselling book series The Mortal Instruments by Cassandra Clare.
Jessica Postigo penned the script which is based on the first book in the series, "City of Bones."
In "City of Bones," set in contemporary New York City, a seemingly ordinary teenager Clary Fray, discovers she is the descendant of a line of Shadowhunters, a secret cadre of warriors dedicated to driving demons out of our world. When Clary's mother disappears, she must join a daring group of young Shadowhunters on an adventure, which leads her through a city filled with mischievous fairies, eccentric warlocks, werewolf gangs and other strange creatures.
The Mortal Instruments is a series of four novels published by Margaret K. McElderry Books, a division of Simon & Schuster, Inc., including "City of Bones," "City of Ashes," "City of Glass," and the upcoming "City of Fallen Angels."
