City of Heavenly Fire (TMI fan fiction)

Sebastian is out for revenge, and he won't stop until he gets it. Now that he lost the first battle --which he very much intended to win swiftly-- he's even more vicious. And now he's got the help of what might just be the most powerful warlock to ever walk this earth. While Shadowhunter's continue to disappear, Sebastian is growing his army. And brother Zacharia is hiding one of the biggest secrets that could possibly cost them the Infernal War. Questions start to pop up about him. Who exactly is he? Why does he have so much concern about the Herondale's? What made him convert into a Silent Brother? With even more troubles, Maureen is out there and carelessly killing innocent human beings. She's snapped and has turned into a cold-blooded killer whose only concern is getting Simon to admit to being her boyfriend. Along with all these horrible things, Jace is still glowing. They're trying desperately to find a cure for the heavenly fire, but the way things are going, they just might lose everything. Will love be their salvation or destruction?
