what book does clary and jace find out they are not related
City of Glass (Clare novel) After a few days, they have a funeral for the people who were killed in the attack. Later that day, Simon meets up with Isabelle to comfort her as Jace walks Clary back to Amatis's place. Later that night, Jace comes to Clary’s place and sleeps with her and in the morning leaves a note. When Clary gets downstairs to save Jace from his mistake, she meets her mother, which she reacts with anger. Later, her mother tells her the truth: Jace was raised by Valentine, but is not his biological son, but rather Sebastian is, and by extension Clary's brother. Clary runs to the Accord Hall to work out a plan to make both Shadowhunters and Downworlders fight together, and during the decision process, Jocelyn, Clary’s mom, releases the truth, and in the end, the Clave decides that both can work together to fight the battle. This allows Clary to use her rune abilities to create a bond that allows them to fight together. While Jace is in a battle with Sebastian, he discovers Valentine raised the Angel Raziel, which was raised when the Mortal Sword stabbed into Jace's heart. The angel rose, but the angel killed Valentine and granted Clary’s wish to bring Jace back. The story ends with the confession of love between Jocelyn and Luke.[3]
