Still many questions left by the end of this book! 
 - I'm so happy that Magnus helps the Shadowhunters again. I love him :) 
 - Now we know more about Clary and Jace's "special powers". But, were they born this way or is this an alteration? Why do they have them? Jocelyne couldn't have had a child with a daemon since the baby would have been death born as she was marked... So why? 
 - I hate the fact that Jace and Clary can't be together as of now... Annoying! 
 - What did the Inquisitrice said to Jace before she died? It was after she saw the star on Jace's clavicle. Same as Clary on her shoulder... 
 Overall, I'll keep reading because I want more details and answers!'
