City of Glass by Casssandra Clare
I couldn't find a summary of the book, but trust me, this series is awesome! There's two books that come before this one, City of Bones and City of Ashes, and they are both amazing. I am so excited for the March 24 release date and it's over two months away! I'm also happy because I just found out that Cassandra Clare is coming near me for the book tour and I'm planning on going.
