City Of Black Magic

After the wars with Valentine and Sebastian Morgernstern, the Nephilim are attempting to raise their numbers once again. This, however, is worried to be an even more difficult task with the happenings in New Orleans, Louisiana, a city notorious for "black magic." In the Shadow World, New Orleans is one of the few cities where the Downworlders are more prominent than the Shadowhunters; yet, they live together, mostly without huge problems. Though tensions rise with sort of illness that seems to be rising, passing only through Shadowhunters. The warriors of angel blood become weak, then bed-ridden as their blood is noticed to change. Lastly, they die.
As Shadowhunters used to fighting demons learn to battle a disease, there are questions as to who can be trusted, who can be saved, and who can be protected?
