Ave Atque Vale, Clary

What if Clary was raised by Valentine, but while traveling, the Clave caught them, and Clary was sent to the orphanage in Idris. But not any ordinary orphanage, one which trains the orphans to go on missions. While Clary Morgenstern, and her team, Spitfire, go on their first long distance mission to New York, what happens when Valentine shows up, and proposes an idea that could change everything?
