Let me start off by saying, I LOVE THIS SERIES. I might even like this more then The Mortal Instruments (gasp!). This author has a way of pulling you into her books, making you not want to stop reading and finish the entire book in one sitting. 
 For the characters, I'm not super fond of Tessa. She seems to be very judgemental in certain situations, and just not likable all the time. Jem is probably one of my favorite characters. Hes sweet, easy to like, and I fell in love instantly. Will is a deep and mysterious boy, who we're just now finding out about in this book. Its hard not to like him once you know his past. 
 I don't like how they portrayed Jessamine in this book. I love her character, and I feel that the author ruined her in the second book on this series. Shes made to be weak, and a traitor. 
 I love the story line of this whole series, and how its based in the 1800's. It really has a nice feel to it! Most of the characters are easy to relate to, and it keeps you captivated. The idea of Shadowhunters before The Mortal Instruments really drew me in to reading this series. This book has some of the characters from the Mortal Instruments, and it shows how certain things were invented before that series. It really gives you a look in the past to see how things became the way they are. 
 We finally find out some things about Mortmain, and some of what he plans to do with Tessa. There are sad parts, and happy parts, and all around crazy parts. If you're thinking about reading this series, or have already read the first one but can't decide if you want to read Clockwork Prince, I highly recommend it! I give this book a 5/5 stars.
