The Mortal Instruments: City of Fallen Dream...
After Clary and Jace's make out session at Simon's Band's gig, Sebastian starts messing with Clary's head so she dreams and hallucinates of Jace killing her. She stops eating and sleeping so much that Jocelyn decides to take her to a mundane asylum. Of course though Jace pulls Clary through. Sebastian senses this and takes things in his own hands, killing Clary as the start. Ithuriel and Raziel are creating Angels from Shadowhunters. The war against Sebastian quickly comes and Clary loses something important or does she? Marriages, proposals, deaths and resurrections await the gang. My version of the fourth book and how the series should end from there. Love is tested through death but some loves are meant to last forever.
