Saving Valentine's Daughter (Clace)

Okay, so I decided to make a Clace fanfic so here I go. . .

Jace Lightwood has been on a mission, along with Alec and Isabelle, to find the daughter of Valentine. Clarissa Morgenstern (Goes by Clary) had angel blood submerged in her body when she was born. Valentine believes that he made the Shadow World's strongest Shadowhunter ever. As the days go by, Jace realizes how important Clary is to her. But will one secret mess up their growing relationship?
