After witnessing a murder that only she can see, Clary finds out that she is a Shadowhunter, just like her mother. Unfortunately her mother is soon kidnapped. The murderers turns out to be three Shadowhunters, Jace, Alec, and Isabelle, killing a demon, because that is their job. Clary has to grow as a Shadowhunter and learn to use her new powers to try and save her mother. It was so hard to put this book down, especially towards the end. There was an unexpected twist because I was not sure I read it right. It had a little bit of everything, from adventure and even a little bit of romance. It was fantastic and I would surly recommend it to anybody looking for a good book to read.
