 This rocked!!!!!!!!!! 
 I needed something to read one night, so I remembered this series. I found myself buying the book, then finishing it within 4 days time. Clary Fray, Jace Lightwood, Simon Lewis, Isabelle and Alec Lightwood, and Magnus Bane are back in book 4 of The Mortal Instruments by Cassandra Clare! The main conflict? Someone is murdering Shadowhunters who used to be in Valentine's circle, causing unrest and tension between the Downworlders and Shadowhunters. 
 This book......Just cracked me up so freaking bad. It was hilarious, with witty remarks and just outright awesomeness. Want some examples? ^-^ I have plenty. 
 "Is this one of those keep-your-friends-close-and-your-enemies-closer things?" 
 "I though it was keep your friends close so you have someone to drive the car when you sneak over to your enemy's house at night and throw up in his mailbox." 
 "As long as everyone's wearing their own pants." 
 "I see I have come in on a fascinating moment in the conversation." 
 Simon looked from one of them to the other, and shook his head. " When did you two get so buddy-buddy? Last night it was all, 'I'm the most elite warrior!' 'No, I'm the most elite warrior!' And today you're playing Halo and giving each other props for good ideas." 
 "If we're going to the Silent City, you might want to get dressed. I mean, I appreciate the bra-and-panties look, but I don't know if the Silent Brothers will. There are only a few of the left, and I don't want the to die of excitement." 
 See what I mean? It's awesome! 
 Now, I have something to say. There's a minor character in this book. A girl that's 14-years old. She was sweet and kind....But the way the author wrote it made the teenager seem like she was ten. *facepalm* Why?! I'm a teenager, as you all know, and I know that that character should've been a bit more mature. 
 I have just one more negative comment. Jace.....was a bit mushy in this book. :( And I think I can understand why, but I wish that he was like in the previous books, ya know? Not as mushy. He was still the king of sarcasm though. :) 
 Well, that's pretty much it! I'll be getting the 5th book soon, and watching the City of Bones movie that comes out in August 2013. ;) This book get five stars! Congratz, Cassandra! Good work! LOVE THIS BOOK. 
 I recommend to Cassandra Clare's fans, of course. Ages 13-Adults should take a peek. ;) But only if you've read the previous three books!
