because of his dislike for his name. Jace was given the blood of an angel named Ithuriel by Valentine when Celiné was pregnant with him. This gave him enhanced abilities, even compared to regular Shadowhunters, such as enhanced durability, enhanced speed, and enhanced stealth. For most of the books, Jace's sarcastic, cold remarks and behavior hide his tortured and angry soul. In City of Ashes, his strong "bad-boy" personality makes Maryse Lightwood (his adoptive mother) somewhat scared of him, realising his alikeness to Valentine, who was believed to be his real father until the assumption was proven false in City of Glass. Jace and Clary fall in love in City of Bones, making Clary the only girl Jace has developed real genuine feelings for, but after they find out they are "siblings", each attempts to get over the other by dating other people. He is naturally overprotective and caring for her, although Clary does not see this due to her internal suffering. At the end of the third novel, City of Glass, Jocelyn contradicts Valentine's avowal that Jace and Clary are siblings, telling Clary that Jace is actually the son of Celine and Stephen Herondale. The truth frees Jace and Clary from the torture of having seemingly incestuous feelings for each other, allowing them to accept their mutual feelings and become a "real" couple. By Lady Midnight, the first book in the third series (The Dark Artifices) of Shadowhunters, Jace has proposed to Clary. They are 23 and 24 respectively. However, she refuses him, because she believes that she is going to die (she has been having visions of her lying dead, and Jace is crying over her dead body). Clary admits to Emma at the beginning of the second book, Lord of Shadows, that Jace has, in fact, proposed to her, but she is afraid that she will die, leaving Jace without his love/ wife. Since she considers marriage as a promise of staying, she refuses his proposal in order to focus on their mission. By Queen of Air And Darkness, however, we discover that she had, in fact, been having visions of Thule, where Jace is Endarkened and Clary is dead. Clary proposes to Jace, and he agrees. We see the chapter end on them kissing, and the Midnight Flower opens in front of them, unnoticed. Physical appearance Jace has wavy dark golden-blond hair and dark golden eyes.
