***SPOILER ALERT!*** 
 Clary is out to the City of Glass to find a Warlock who has the antidote to her mother's coma. Once she's in the City of Glass (illegally). She goes out and searches for Jace to face him to his lies and discovers that he isn't all that upset and actually walks in a romantic scene. While she confronts Jace, She is led to know that she is the cause of his attitudes, and reminds her that from the day that she entered in his life, she destroyed it. Well, he hurt her pretty bad. And then she ends up kisses his 'cousin' who isn't his cousin who is really Clary's brother. 
 Simon is kept prisoner by the Clave. Why? Well first of all he is a Vampire and he isn't suppose to be in the City of Glass. And who else to take advantage of that? Yes, the Clave. Dear old Simon is very loyal to Clary and keeps his mouth shut. Besides he loves her, or does he? 
 When Jace died, I was like 'What the crap!' and tears came to my eyes. But even more when Clary asked the Angel to give him back to her. Like I said they were meant to be. 
 I loved this book, and I have a feeling I am going to love City of Fallen Angels as well. If you liked Harry Potter series, then you'll like The Mortal Instruments series. :)
