City of Glass is written by Classandra Clare. I think the City of Glass is a very fitting title for this book, because that's exactly how the Shadowhunter's city look like, a city made out of glass. I hope I could actually see it. It sounds so amazing and beautiful. In this book, Clary meets a new character, Sebastian. Their relationship is kind of weird because even though Clary didn't know that they are siblings, Sebastian did. This made their relationship weird. Sebastian was the opposite of Shadow hunters, he has blood of Lilith, a demon, in his veins.

City of Fallen Angels is written by Classandra Clare. This is the fourth book of The Mortal Instrument series. This series is really awesome and the author makes me feel like I'm a bystander in the story, like I'm in the story looking at the events happening. I also love the way Cassandra Clare write this story. In this story, Jace and Clary can finally be together.

City of Lost Souls is written by Classandra Clare. In the City of Lost Souls, Jace somehow became extremely ignorant to a lot of things. He listens to everything Sebastian says. Clary fakes that she will be staying with Jace and Sebastian and they bought it. In end of the story, there were a massacre of shadow hunters. Clary also gained a sword. The sword's owner is the Archangel, Michael. She uses the sword to sever the link between Jace and Sebastian, by stabbing Jace. Jace almost died and when he healed, new problems surfaced.

City of Heavenly Fire is written by Classandra Clare. I loved the ending of this book, but is also a bit sad that this is the end of this series. There are some surprising things in the story. Jace has the heaven's fire in his body and Clary somehow sealed the fire into her sword. In the end she stabbed Sebastian with it and he died. Magnus Bane, the warlock, sacrificed himself so that the rest of his companions could leave Asmodeus's realm. In the end of the story, Jace chose to live on as a Herondale, instead of Lightwood or his original family. Jace is connected to another character in another series also written by Cassandra Clare. I would recommend these series to everyone.
