The Mortal Instruments: The Psychotic Siblings

Set in City of Glass, Clarissa Morgenstern is part demon and part shadowhunter. She had been fed the blood of Lilith while she was still in her mothers stomach. Jocelyn never ran away from Valentine who had experimented on their first child and found Jonathan to be too cruel. He tried Angel blood on a girl from his Circle but she had killed herself at 8 months with twins. Valentine took both boy and girl from the body and raised both twins but they were too pationate so he thought about turning a girl Nephilim to half demon, but the result was worse then Jonathan's. Valentine had raised all four children kepping the demon siblings together and leaving the Angel Twins together. Valentine became harder and stricter after Jocelyn was killed by Shadowhunters. But what will happen when Valentine sends the siblings to infultrate Idris and Clarissa meets Angel boy - the boy who she had sneaked out to meet several times while growing up? Will Jace recognize her? And will she learn to love or stay as heartless as she had always been?
