City of Glass is the third book in the Mortal Instruments series. It is my understanding it was originally a trilogy, which Cassandra decided to expand into a 6 book series. The ending definitely felt like the conclusion of the series. Everything comes together nicely and I was very content with how she left each of the characters.
From what I have heard, that isn't the feeling readers have had that continued reading books 4 through 6. For that reason, I am going to consider this series complete for the time being and move onto Cassandra’s Infernal Devices series, which numerous people have told me I HAVE to read.
I love the Shadowhunter world Cassandra has created. The battles against Valentine and his demons added the necessary danger and excitement to keep the pages turning. I also enjoyed watching the characters grow though out the series. Simon gains a tremendous amount of confidence in this installment as he comes to terms with being a vampire and embraces his new talents. I also enjoyed seeing Alec open up about his relationship with Magnus. Perhaps the greatest revelation was discovering who Sebastian really is and how that news impacts the rest of the Shadowhunters.
What I enjoyed the most about City of Glass is that it brought the Shadowhunters and Downworlders together to fight for a common cause. They all have unique abilities, so it always surprised me that the Shadowhunters looked down upon the vampires, warlocks, fae, and werewolves. If only they would have aligned themselves sooner, a great deal of death and evil likely could have been prevented. The alliance also makes it possible for all of our favorite characters to live together peacefully, which definitely contributes to the warm and fuzzy ending to this trilogy.
I would definitely recommend this series to any YA fan. If you have read the last three books in the series, I would love to hear your thoughts. Should I read them or not?
