We all know the story...
Clary finds out she's a shadowhunter and is taken in by the inhabitants of the New York Institute. But what if someone else gets to her first, someone on the other side? And what if Clary was already a shadowhunter in the past but her memories were taken from her by a certain brother of hers?
Clary is forced to face her brother and herself in a fight for her freedom and a fight to save the shadowhunter race from the demon that is Sebastian Morgenstern. Can she do it?

Disclaimer: all characters from 'The Mortal Instruments' books belong to Cassandra Clare as does the initial idea. All i really own are the characters i create which will probably pop up later in the story.
