Cassandra Clare returns to poor form after an above-average City of Ashes. Characters have about-faces; are made unbelievable and crude, especially Simon. Clary is as ridiculous as ever, sprouting extra powers as need demands, and she is as compelling as a piece of cheese. The primary antagonist, Valentine, is an unoriginal cardboard cutout, with goals taken straight from Rowling's Voldemort. Valentine inspires no fear. Jace is a waste of space. The incest plotline(s) are unnecessary and overblown. The author wusses out on the 'dramatic character death' front, killing off an extremely minor character, instead of someone who really deserved it, who was brought back to life by an angel - Can you say Deus ex Machina? Plot is stringed together by a series of coincidence. Backstory is ridiculous and the reader has to endure several pages of forced exposition on multiple occasions. Ultimately, the book is overlong, with a sagging middle, irrelevant characters, and borders on plagiarism on several accounts. The writing is poor, and Clare does not know how to use an adverb, or a semi-colon. Or a comma. But you do get a happy ending!! (And another book; the fourth in the trilogy. Cassandra Clare is an official trilogy creep.)

I don't recommend this book for younger tweens. City of glass is even more violent than the first two books and there is even more sexual scenes than the first two also. Personally I think that the whole series is great, I really loved all of them, but as a Christian girl I find the demonic stuff a little disturbing.

I loved the whole thing. I would totally choose this world with Jace, Isabelle, Alec, Simon, and Magnus than any other book-world! There's a bit more kissing 'n' stuff than the others, but the book is so amazing!

LOVE IT!! I COULDN'T PUT IT DOWN!

Absoultly amazing!! The best of the series. It blew my mind!

I love it! It was a book for kids that like trills and chills and love, if you read this you will fall in love with Jace or Clary!

I really loved this book. i read it one year ago during the Twilight craze ( at that time I was over the whole twilight thing) and I actually thought it was better than all of the Twilight series. The plot is much more interesting, and the Clary is not such a damsel in distress like Bella. I like that Clary is tough and can stand on her own. The Damsel in distress thing is just so typical now. City of Glass(in fact the whole series) kepp you thinking , and madly flipping the pages, hoping and cheering for the main characters, and reading all through the night. it is so good, that at the upsetting parts, I actually slammed my book on my desk in class once. Embarresing, but it is really that good.

Great book!

Go out and buy the whole series. You will have something to talk about for months with your friends. Can't wait till the next book comes out
