I purposely read this after City of Heavenly Fire was released because I know this is going to be cliffhanger and waiting for the sequel was an AGONY. Some of you guys are already reading or finished with City of Heavenly Fire, and I'm trying to avoid SPOILERS (good thing I wasn't spoiled....YET.Thank goodness!) around here. 
 I absolutely love this better than City of Fallen Angels. I love the plot twists and the story gets more complicated with a new villain and there are character improvements. As always, Clary is still reckless but less whiny. Her unconditional love for Jace was just admiring. No one ever gets in her way even it's dangerous to save her Jace. I love her for that. I miss Jace's sarcasm and I find him hotter in this book(You know what I mean).I.LOVE.THIS.GUY. Plus I ship Simon and Isabelle. I'm definitely looking forward what will happen on these two and they need to confess on each other's feelings! Damn it!!! 
 I am not really a fan of gay romance, BUT Alec and Magnus are in exception. At the end of the book, (view spoiler)[their relationship goes into rocks. Seriously, Alec. You may be mortal and Magnus wasn't JUST ENJOY BEING WITH HIM. He loves you to bits. uggh! Stupid love (hide spoiler)] 
 Lastly, Sebastian. What a freaking bastard. I was almost... ALMOST convinced he has a good purpose, as it turns out... he wasn't. That bastard needs to die. ASAP. Go to inferno. 
 This book was impressive and a page turner. It's a series worth reading for. If you haven't read this series or you've just started it, I suggest you read The Infernal Devices first before reading CoLS. I think I was spoiled because: (view spoiler)[Will Herondale died? Oh hell. I think this is a SPOILER. (hide spoiler)]. I can't wait to grab a copy of CoHF! <3
