Reversed City {Under Construction}

#twistfatechallenge
What happens when Sebastian is raised again? Everyone would start to panic, then they find out that he actually wants the Downworlders and Shadowhunters to survive, to live. What would happen when Jace, Simon, Isabelle, Alec, or Magnus can't find Clary? They look everywhere just to find out that she's been running around, killing Downworlders, just as Sebastian had before. Will Jace and the other Shadowhunters find a way to stop her? Or will she forever rule the world as their Evil Queen like Sebastian once wanted?
(This was originally for the Twist Fate Challenge and I had a word limit, so it wasn't that good, and now I will rewrite it the way I want to)
