Hidden Secrets

I know many stories have a similar plot but screw it. I'll add another one to the bundle.

Clarissa Morganstern was never hid from the shadow world. Instead, she was trained by her father and mother. Both Clarissa and Jonathan are normal shadowhunters, until one day when they stumbled across a demon nest at a young age. After this horrifying event, the Morganstern's decided to move away from civilization. 5 years later, they show themselves again. Though, not with 4 people. But 2. After their presence was known and feared, the Morganstern's decided to try and live a normal life. Glamoured, they stumbled into the New York Institute, pretending to be injured people, in need of help. What would people do, when the shadowhunters of the New York institute meet the people that have many secrets of their own?
