City of Fallen Angels (The Mortal Instruments Book #4) by Cassandra Clare
(Summary taken from inside the book jacket) "The Mortal War is over, and 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 important of all--Clary can finally call Jace her boyfriend. But nothing comes without a price. Someone is murdering Shadowhunters who used to be in Valentine's Circle, 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 that he's a vampire and now he's homeless. Everywhere he turns, someone wants him on their side--along with the power of the curse that's wrecking his life. And they're willing to do anything to get what they want. At the same time he's dating two beautiful, dangerous girls--neither of whom knows about the other. When Jace begins to pull away from Clary without explaining why, she 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."
Wow. This book is so good. If you liked the first three then you definitely need to read this one. It is action packed and has some crazy twists and turns. I wasn't sure where it was headed, but it is crazy. And the ending.....oh the ending. I closed the book and screamed, "NO! It can't end like that! AAAhhhhhh!!!" And then I thought....May is a very long time to wait for the next one (it's November). Oh man!
This book is a lot racier than the previous three and there is a lot of language. There is a lot of "physical intimacy" talk (and one scene in which they do all but, and you know it is their intent), along with Alec and Magnus' homosexual relationship. There is also a lot of violence. There is a part that deals with babies that is awful and grotesque and graphic. Haha...and I liked this book? Umm, yep!
Rating: PG-13 For all of the above paragraph.
