Book Summary Via Goodreads:
"In this dazzling and long-awaited conclusion to the acclaimed Mortal Instruments series, Clary and her friends fight the greatest evil they have ever faced:
Clary's own brother.
Sebastian Morgenstern is on the move, systematically turning Shadowhunter against Shadowhunter. Bearing the Infernal Cup, he transforms Shadowhunters into creatures out of a nightmare, tearing apart families and lovers as the ranks of his Endarkened army swell.
The embattled Shadowhunters withdraw to Idris - but not even the famed demon towers of Alicante can keep Sebastian at bay. And with the Nephilim trapped in Idris, who will guard the world against demons?
When one of the greatest betrayals the Nephilim have ever known is revealed, Clary, Jace, Isabelle, Simon, and Alec must flee - even if their journey takes them deep into the demon realms, where no Shadowhunter has set foot before, and from which no human being has ever returned...
Love will be sacrificed and lives lost in the terrible battle for the fate of the word in the thrilling final installment of the classic urban fantasy series The Mortal Instruments!"
The bells toll and the heavens sing praises, this book was.. holy waffle batter... it was amazing.
Barely into the second chapter and shit is already hitting fans. And it all started on somewhat of a cheerful note. Sure everybody was on edge from what had happened a month before, but they were trying to have a semblance of normalcy.
I am so glad we get to meet Emma Carstairs in this book since she is going to be the focus of the next Shadowhunter series. It was pretty important for them to set up what kind of character ahead of time. By the way, she's awesome.
That first death, I was expecting it to be him, just not that early. Even though I was expecting him to be one of the people to die I still sat staring at the page with a look of shock for about a minute. Clary continued to not be a useless lump, and Simon is awesome as always.
There was so much action and I was on edge the entire time reading this book. The traitors, not really surprising considering the events from the last book. I saw that one a million miles away. The Shadowhunters shouldn't have trusted them any further than Church could have thrown them.
So much happens through this book, and it wasn't until the last 30 pages when the full on battle really happened. But we got a nice scene in a cave with Jace and Clary. And some nice romantic scenes with Izzy and Simon, those tied in with some comedy to lighten the mood some more from their dire situations.
Then things go down. And, oh man I was not expecting that to happen. Maia, I actually like her now. Little use it does not that this series is over and it's unlikely we'll see her again. Clary is actually really clever in this book too. Still a bamf, but also really smart. (because let's face it she wasn't very bright in the first three/four books.)
When that thing happened to Simon, I started crying. All those people died and the thing that happened to him made me cry.
I am really excited for the other Shadowhunter books Cassie Clare is writing. Although I will say it right here and now, I want one of the unnamed series she's writing to be set in the future where Jace and Clary are running the New York institute. I need that, and I doubt I'm alone.
Bottom line read this series. Sure City of Fallen Angels is one of the weakest books in the series, but in the end, it's worth reading.
