If the legends are true, the dead don't stay that way long in Egypt. For the NUMA crew, the promise of these old stories might be their only hope of survival. When nearly the entire team is exposed to a dangerous substance called the Black Mist while working on the Italian island of Lampedusa, they and the rest of the town fall into a deathlike sleep. With their own men and women on the line, Kurt Austin and Joe Zavala must race to find a cure before it's too late. From Europe to the Middle East and back again, Kurt, Joe, and what's left of NUMA will hunt down a foe more powerful than they can imagine. Desperate to save their friends, they'll place their trust in a mysterious new ally, a doctor who knows more than she lets on. But this may not be their only sacrifice, as Kurt and Joe learn that the Black Mist is only part of the terror in store for those who would oppose Osiris. After all, it's called the City of the Dead for a reason."
