this third book in the trilogy is just as amazing as the first and the second. It begins a week after the 2nd ended, and by then Jace has become completely desperate to protect Clary from any harm at all. he convinces himself that the only way to keep her safe is to keep her away from him and any other shadowhunters. She doesn't understand why he can't stand to be around her anymore, and doesn't realize that he is suffering the exact same thing she is- but i wont give it away. just trust me that it is the perfect ending to probably the best fictional series and epic love story i have ever read.
