The Mortal Instruments In My Mind!

This is what I think the mortal instruments should be like.
Clary grows up with her Mother Joyclyn and her stepfather Luke. He's not really her stepfather they are just as close.
At the age of 4 she gets kidnapped by her own father Valentine. She lives with her brother Johnathon too. They are very close like very. At the age of 10 she she started going to an institute with a boy named Jace and twins Alec and Isabelle. They all grew very close. At home Clary and Sebastian started to get abused by their father. Clary never told anyone but she hid her bruises by runes. So no one ever knew.
Clary finally couldn't take it anymore and erased Jaces' Alecs' and Izzys' memory of her.
She went back to Joyclyn and Luke and found a new bestie Simon. A couple years later Sebastian came to visit and stayed there. When Clary turned 18 she went to a dance club called Pandemonium and saw Jace Alec and Izzy. The sad part was they didn't recognize her. They were killing a demon and she started to help out. They were confused.... she knew why but it still hurt her.
