Part One: No Evil Angel

The book opens with Simon returning home, and then he finds out that there are a lot of symbols that form a barrier so he can't enter the house. After that, he talked to his mom, only to feel more rejected when she says he killed the "real" Simon. Things become more tense when he learns from Clary that Jace is currently missing and untraceable. Clary and the rest of the group manages to gain the assistance of the Seelie Queen, but at the cost of two Faerie rings that would allow the wearers to communicate telepathically. Desperate, Clary agrees to the terms and while searching for the rings in a Shadowhunter library, accidentally observes Jace enter the library and speak in friendly terms with Sebastian- which confuses Clary, who had been hiding during the conversation.

That night Clary wakes to find Jace lying in bed with her, asking her to come with him. Shortly after this, Sebastian enters the room- something that is discovered by Jocelyn, who screams and alerts others to their presence. The two leave, but promise to return for Clary. She eventually decides to join the two men as a spy while using the Faerie rings to communicate with Simon. During this time Clary realizes that Jace has been possessed by Sebastian, as he acts more like Sebastian than himself. Jace manages to temporarily shake off the possession and explain that Sebastian is planning to use Lilith's blood to create an army of dark Shadowhunters using the second Mortal Cup and will turn himself into the Clave, as he'd rather die than continue to be possessed. He was only able to regain control due to the rune controlling him having received damage, which would also cause him to eventually die. Not wanting Jace's death, Clary calls Sebastian in and asks him to heal the rune. Meanwhile, Simon and the others summon Raziel, who gives Simon a blade of Heaven named Glorious but at the cost of Simon's Mark of Cain.

Clary is later shown to be searching Sebastian's room, where she discovers her Faerie ring. She manages to alert Simon of most of Sebastian's plan and tells him to come to the Seventh Sacred Site, but is caught midway through by Sebastian and is forced to destroy the Faerie ring. The two then fight and Sebastian unsuccessfully tries to rape Clary, who manages to escape. She ends up going to the Seventh Site, where Simon gives Clary Raziel's sword, which she uses to hunt Sebastian. Unable to reach Sebastian, Clary uses the Angel blade and stabs Jace, believing that it won't kill him as his heart is more good than evil. Jace is set alight, leading the others to believe that he is dead.
