To Rely On Each Other

Lily Collins stopped by a book signing by Cassandra Clare yesterday, March 21, in Los Angeles. She was there to support the author who also penned The Mortal Instruments: City of Bones.

Lily is starring in the film version of Clare’s novel and decided to attend the signing as a sing of thanks to Clare. Clare was there to read from her new novel Clockwork Princess.

Lily’s new movie arrives in theaters August 23!
