I Любовь the ending of 'City of Glass' too and I don't want that to be ruined either, but I just took a chance and just read it. I was too excited for it.
For me, it was worth Чтение to see where the characters were going and what the plot was going to be like in this trilogy. It was darker than the other Книги and there are new characters. I'm not sure how I feel about this book compared to the others. I might make a decision on that after I've read the other two Книги in the series since CoFA is kind of the start of a new trilogy in the MI series. But I did enjoy Чтение it.
There isn't еще of Simon's POV than everyone elses. Cassie explains this
link "City of Fallen Angels, City of Остаться в живых Souls, and City of Heavenly огонь are all told from mixed third-person viewpoints. That means some scenes are told from Clary’s point of view, some from Jace’s, some from Simon’s, etc. Much like City of Glass. None of the Книги are told from only one point of view. None of the Книги are told from Simon’s point of view only, no matter what Ты may have heard. They are all mixed point of of view." Most people from the reviews and Комментарии that I've seen online/on Cassie's Twitter сказал(-а) that they liked Simon еще actually after Чтение the book and that it was a nice change to see how his life is. So I'm not sure if you're opinion will change of Simon, but Ты never know until Ты read it. Hope that helped.
