I can't believe I'm halfway through this series already! So far, the series has been pretty constant, which is good, because I have a general idea of what to expect, but at the same time, I keep hoping for something unexpected to happen. 
 Jace and Clary finally learn they are not siblings after all (which isn't that surprising), and who her real brother is. And at least Jace and Clary can be together without the ick factor of being related. Those two things were pretty predictable, and it was a matter of when they would be revealed. And I can't remember if we see Clary's mother when she's not in a coma or whatever (if we do, it's totally not memorable). I'm not sure how I feel about her, because I've gotten used to her not being around. 
 In order to save Clary's mother, we finally get to go to the City Of Glass. Sadly, I wasn't impressed with this city that's supposed to be amazing. I'm not sure if it's because of all of the build-up surrounding the City or it just wasn't described very well (because it wasn't, in my opinion) or if it's just because we spent of the book in a couple places. Or some combination of factors. 
 There's a lot of action, and there is also quite the battle as Valentine continues his quest to take over the Shadowhunter world. It doesn't end well for him, of course, and I'm definitely glad he's no longer around. Still, I'm not completely convinced that he's truly dead, even though it seems pretty permanent. 
 Here's what I'm wondering: I know that the summary above said that this book was the final installment of the series, and this book does seem to wrap up the entire series pretty well. But there are three books after this one, so I'm wondering if maybe it's a misprint and six books were intended all along, or if it was meant to be three and was later extended to six. Which I think is partly why I'm not entirely convinced that Valentine is actually dead. And if he really is dead, what's in store for the next three books? 
 Also: I find the timeline interesting, since the first three books take place over several weeks. Which is hard to believe, and it feels like it should have happened over a longer period. Things definitely move at a really fast pace, and there's a lot going in. Which makes it easy to read, and you want to keep going, but even with City Of Glass, it feels like things could have been slowed down. At least a little. 
 Let's Rate It: I liked City Of Glass, and it was a fun read. I'm definitely curious to see where things go, since City Of Glass resolved the events of the first half of the series pretty well. City Of Glass gets 3 stars.
