Clary learns that Valentine Morgenstern, who is supposed to be long dead but truly is not, the main antagonist of the series, is her biological father and her mother's husband. At the end of City of Bones, Valentine tells them that Clary and Jace are siblings — which, they discover later in the series, is a lie. In the second book of the series, City of Ashes, Clary dates her best friend Simon, who has for a long time had a crush on her, in order to forget Jace during the torturous time of believing him to be her brother. She is told by the Seelie Queen that she and Jace are Valentine's experiments but mysteriously does not explain further. She finds out later that she was exposed to powdered Angel blood through her mother who consumed it unknowingly by Valentine when she was pregnant with Clary. This angelic blood granted her the ability to create runes that do not exist and amplify the power of existing runes for herself. At the end of the second novel, Clary finds that an old friend of her mother, Madeleine, knows how to wake her mother, who has been in a magical coma since the first book.
