The war against Valentine ended and the Clary won! So everything is supposed to be perfect since Jace and Clary can finally be together...except for the fact that Jace has started to act distant from Clary. There have also been mysterious deaths of Shadowhunters and the death of mundane babies who look suspiciously like they were trying to be turned into half demons.
I thought this book was..eh because it felt like it was kind of a letdown compared to City of Glass, which ended on a perfect note. Clary and Jace's relationship just seem to deteriorate because Jace didn't tell her this one secret which ultimately could have broken them up for good.
I would recommend it only if you have read the other books. But besides from that, it wasn't the best book in the world.
