subject of the Queen's, she goes to the Seelie Queen's palace where she has to beg for help due to the limited resources. The Seelie Queen has requested that Clary is allowed to steal the faerie rings kept inside the institute. Clary steals the rings but doesn't give them to the Queen because of the appearance of Jace and Sebastian at the library, all healthy looking and safe. Afterwards, Clary accepts their offer of coming to them. When the plan of Sebastian was finally revealed to her, she couldn't believe what could happen. When Sebastian finds her communicating with Simon through the Faerie rings, he fights her and attempts to rape her. At the enchantment ceremony, she was surprised when Amatis was turned into a dark Shadowhunter by the blood of Lilith. At the same time, Magnus, Alec, Maryse, Isabelle, and Simon arrived, with Glorious in hand. When Glorious was handed to her, she struck Jace, the mark of Lilith burning, making him cry out in pain. In the epilogue, she was concerned why she couldn't visit Jace because of her thoughts telling her she almost killed Jace, but reassured by Isabelle she didn't do anything to make Jace mad. She visited Jace, but she almost thought she wasn't going to be allowed to go in due to Brother Zachariah. By the consent of Brother Zachariah, she entered, hugging Jace and reaffirming their relationship. Finally in City of Heavenly Fire, Sebastian has taken many shadowhunters and turned them into his Endarkened. The remaining shadowhunters retreat to Idris for safety. Sebastian offers to leave them alone if he is given Clary and Jace. Before the Clave can make a decision Clary, Jace, Simon, Isabelle and Alec sneak off to Edom, the demon realm Sebastian is hiding in; he has Jocelyn, Luke, Magnus and Raphael prisoner. After spending days trying to find him they come upon his castle, a dark version of Alicante. Sebastian offers Clary a place next to him, in exchange for leaving everyone she knows and all of the Shadowhunters alone. She accepts it, knowing that she has to keep everyone safe. When Sebastian is momentarily distracted she stabs him with the Morgenstern blade, containing Heavenly Fire. He is returned to the brother that she could have had before he then dies. The group manage to escape after Simon gives up his immortality and memories of the Shadow World
