Rating on "City of Heavenly Fire"

I just finished "City of Heavenly Fire" yesterday and overall it was a good book. I would give it 4 out of 5 stars because I liked that none of my favorite characters died, but at the same time, they announced 6 character deaths before the book came out in May, I was really anticipating who would die, but none of them really made me sad in any way, there were only deaths of 5 side characters and one main character which happened to be the main antagonist. I would recommend it to teens who like any stories with vampires, werewolves, demons, etc. The main "bad guy" died, but I would much rather have preferred that at least one or 2 of the main characters died while they were trying to get to him. It just seemed like a disappointment to me that even though it was announced there were 6 character deaths, they weren't really major. This is why I'd give "City of Heavenly Fire" 4 out of 5 stars.
