good book

The Mortal Instruments are amazing! Cassandra Clare is a genius. I love her books and I looove Jace!! City of Lost Souls comes out today!!

Definitely not as great as the others. I regret reading it. The series deserved to end at City Of Glass.

And the saga continues. Returning from a seemingly successful trip to Idris, Clary is adjusting to her new life. She is learning the skills of a Shadowhunter, adjusting to her mother's new relationship, and beginning a relationship of her own, with Jace. But Jace seems to be a little less interested in her than she expected, and what's with the dead baby in the news. Meanwhile Simon is also adjusting to his new life as a vampire, and trying to figure out how to tell his family. He is also being followed, but he isn't sure why or by who. There is lots going on here, and the bad guys aren't vanquished yet. Less huge battles in this one, and more personal issues and smaller interactions. A new character is introduced that looks like he may stay around for a while, and others reappear. Once again, plot leaves us hanging and waiting for the next in the series.

I LOOOOOVE the mortal instruments series i find it very good but a few times my interest wandered but still very good

i loved all 4 of these books but i can't wait until the 5th comes out on may 8th 2012 yayayayay

Cassandra Clare is a very, very good writer ... But I must say after the third book in the Mortal Instruments, a part of my interest in this series has waned. I do enjoy the Infernal Devices series by her more that the Mortal Instruments.

I was a little leery when I heard that Cassandra Clare was writing extending her trilogy into an ongoing series, especially after the disappointment that was Clockwork Angel. Imagine how surprised I was with how good this fourth instalment was? The plot is simple, Clary's mom is finally marrying Luke (yeah!). Meanwhile Clary is continuing her Shadowhunter training. Oh, and did we mention she is still hot and heavy with Jace? Jace, who is pulling away from her emotionally. And then there's Simon. Clary's childhood best friend, Simon, is a vampire who can walk in the daylight is dating two women, neither of whom know there is another. His mother has found out he is a vampire, and let's just say it didn't go well. Finally, he has suddenly become a target of attacks. The Mark of Cain on his forehead return these attacks sevenfold on the attacker, so Simon is safe, but it is troubling that someone is trying to hurt or capture him. But perhaps the most troubling thing going on are the bodies of Shadowhunters that have begun appearing around New York. All former supporters of Valentine, they have shown up in the territories of various Downworlder communities. And how is this link to the corpse of a misformed baby that was found at a local hospital, one with the hands of a demon. A good, solid outing. Jace continues to be the melodramatic, emotionally unavailable bad boy, but Simon's story makes up for that exponentially with his human approach to supernatural problems. Fans will LOVE this book.

This book is a high paced, anticipation filled novel that keeps you drawn in through the whole thing. Similarly to what other people have said, the series could've happily finished on City of Glass, but I'm not complaining! Great read.

Regardless of other peoples comments, it was my favorite book in the series. Sad that series is over though, but I wasn't satisfied with the ending.
