June 2236, Alexandria, Egypt
96 years after the Harbinger Plague.
A human researcher stumbles across a cryptic reference to an ancient Nightwalker stronghold, long thought to be destroyed. His investigation leads him down a road into dark places and forbidden magic, breaching the Gates of Midnight themselves.
The escape of one of the dead back into the world of the living is a disruption of the natural order that the White Wind refuses to allow. Nicholas and his allies must join forces with the Great Powers to locate the fugitive and restore him to his rightful place in Hell. But their enemy has no intention of going quietly, and wastes no time in setting his own plans in motion. For Jiao-long Firstborn walks the Earth once more, and he intends to put the entire human race in chains.
