These are the first four books of The Mortal Instruments Series. These happen to be my favourite books and also, an amazing series. The last book, The City Of Fallen Angels, is the most suspensful and the most outrageously suspensful one of them all. What I love about these boks are the characters and the action that ties with the romance. Even though romance novels are not my favourite, and not many people's favourite, I can honestly say it is a wonderful series. My opinion, is give it a try. It is a long read and a big book, but it is completely worth it.
