The Other Fairchild (Alec Lightwood Fanfic)...
Myrcella Fairchild/Morgenstern is the older sister of Clary Fairchild. She was sent away by her mother Jocelyn Fairchild for her own safety and protection to live with Magnus Bane, the high warlock of Brooklyn because her father, the monster, Valentine, experimented on her. Little did Valentine know his experiments succeeded and she was healthy, alive and most importantly a very powerful Shadowhunter and a Downworlder. Myrcella lived happily with her best friend Magnus until one day she met a raven haired boy and a strawberry blonde who happened to be her younger sister.
DISCLAIMER: I DO NOT OWN ANY OF THE CHARACTERS OR THE STORYLINE BESIDES MYRCELLA FAIRCHILD AND HER STORY. EVERYTHING ELSE BELONGS TO SHADOWHUNTERS TV SHOW AND CASSANDRA CLARE. Also I know Alec is gay and I respect that, but I wanted to write a fanfiction about him being Bi so if you don't like it don't be rude, just don't read it. Though hint hint Malec will always be endgame
