To save her mother's life, Clary must travel to the City of Glass, the ancestral home of the Shadowhunters -- never mind that entering the city without permission is against the Law, and breaking the Law could mean death. To make things worse, she learns that Jace does not want her there, and Simon has been thrown in prison by the Shadowhunters, who are deeply suspicious of a vampire who can withstand sunlight.
As Clary uncovers more about her family's past, she finds an ally in mysterious Shadow-hunter Sebastian. With Valentine mustering the full force of his power to destroy all Shadow-hunters forever, their only chance to defeat him is to fight alongside their eternal enemies. But can Downworlders and Shadowhunters put aside their hatred to work together? While Jace realizes exactly how much he's willing to risk for Clary, can she harness her new found powers to help save the Glass City -- whatever the cost?
You know when you stay up so late reading, even when you know that you have to get up in the morning? Yeah, this book made me stay up till three 'o' clock in the morning. But apart from the fact that it caused sleep loss it was just as amazing as its prequels. The plot line had so many twists, making me jump up and down with excitement. And I have to admit I did shed a few tears at the last chapter (I think... again I cant check, my mother has stolen it). I noticed that this book was slightly more well written than its prequels, which was good, even though it was told in Third Person, which kind of annoys me.
As I said before, the characters in this book are probably the best characters I have read. Before I start gushing about characters, I have to bully Sebastian. He had a very twisted, evil mind (duuu, Chloe, he is the bad guy...), I couldn't stand him. I practically punched the book I hated him so much. Simon became more tolerable in this book, which was good. And Clary was also more like able, as she was a bit irritating in the middle of book two. Jace was great, as ever. And finally, they found out the fact that I already knew from spoiler forums. :)
So yes, I enjoyed this book, probably more than the other books in the series. I cant wait to see what CC writes next, and I will most definitely buy it on the day it comes out.
