This should be pretty obvious and it's been 7 years since this series started but I'll spell it out anyway: Although I try pretty hard to avoid spoilers in my reviews, there will be spoilers for the previous books. So if you're like me and lived under a rock for the last 7 years, start with the first one.
If you made it through City of Fallen Angels, you're rewarded with City of Lost Souls. In COFA, we learned that because Jace and Clary kept his resurrection from the dead a secret, they didn't know Jace needed a special ceremony to protect him from demon interference. Not having that ceremony done enabled Lilith--mother of demons--to control Jace and trick him into resurrecting Clary's real brother, the evil Jonathan/Sebastian. At the end of COFA, Jace and Sebastian are bound in such a way that killing either will kill the other. In COLS, Sebastian completely controls Jace and the two of them embark on a quest to destroy all Shadowhunters. The only thing Clary can do is go deep undercover to try to learn what their plan is.
This book was SO much better than COFA. Sebastian as the Big Bad makes more sense than Lilith. Clary's undercover work with Sebastian and Jace is suspenseful and thrilling. We see Clary start to come into her own as a Shadowhunter and someone who can fight instead of someone who needs protection. COLS is hard to put down and well worth the read.
