I upendo 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 kusoma 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 vitabu 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 vitabu in the series since CoFA is kind of the start of a new trilogy in the MI series. But I did enjoy kusoma it.
There isn't zaidi of Simon's POV than everyone elses. Cassie explains this
link "City of Fallen Angels, City of Lost Souls, and City of Heavenly moto 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 vitabu are told from only one point of view. None of the vitabu are told from Simon’s point of view only, no matter what wewe may have heard. They are all mixed point of of view." Most people from the reviews and maoni that I've seen online/on Cassie's Twitter alisema that they liked Simon zaidi actually after kusoma 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 wewe never know until wewe read it. Hope that helped.
