the mortal instruments jace x reader

She got rescued by Jace Herondale when hurt by a demon she's killing, she's taken to the New York institute by Jace herondale but the reader has a past with the Fairchild's and Lightwood's, and a connection to clary. Read to see what happens
Mostly for people who have read most or all of the mortal instruments books otherwise you might find it hard to understand, if you want to read it anyway, feel free to ask me any questions about the plot and/or characters. Also the begging (the first couple chapters) isn't that great but I promise it gets better :D Enjoy!!
THIS IS NOT A JACE X CLARY!!! DONT EXPEXT ROMANCE BETWEEN THE TWO!
