City of Fallen Angels - Cassandra Clare
The Mortal War is over, and sixteen-year-old Clary Fray is back home in New York, excited about all the possibilities before her. She's training to become a Shadowhunter and to use her unique power. Her mother is getting married to the love of her life. Downworlders and Shadowhunters are at peace at last. And--most importantly of all--she can finally call Jace her boyfriend.
But nothing comes without a price.
Someone is murdering Shadowhunter, provoking tensions between Downworlders and Shadowhunters that could lead to a second, bloody war. Clary's best friend, Simon, can't help her - his mother just found out he's a vampire, and now he's homeless. When Jace begins to pull away from her without explaining why, Clary is forced to delve into the heart of a mystery whose solution reveals her worst nightmare: she herself has set in motion a terrible chain of events that could lead to her losing everything she loves. Even Jace.
4/5 stars (really liked it)
This story takes off after the end of the third book. Clary and Jace are happy together, Simon is a vampire with the mark that Clary put on him to protect him as well as being a Daylighter. But not all is a happy as it seems. Jace is plagued with nightmares, which he's too afraid to share with Clary and begins to pull away from her. Simon is an outcast and there are other Downworlders out to get him and he needs to come to terms that he is no longer human. Also there is Alec and Magnus who are happy on vacation. This story is filled with many of the characters we have grown to love. I can't wait to read the next one.
