The Mortal Cup

What if Clary wasn't the only one who had the sight? What if there was another shadowhunter with Jace, Alec, and Isabelle? Meet Serena and Scarlett. Serena is a badass shadowhunter just like her friends. Scarlett is like Clary, except she's also a shadowhunter. What happens when these two worlds collide? Read and find out. I don't own anything except my OCs.
