The Sleeper's War

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.

An ancient drug will determine humanity's future
Makry ypno. Long Sleep. Lost in the darkness of history for millennia, referenced only in obscure Greek medical texts, this strange plant holds the key to allowing humanity to survive global threats by escaping to the stars. That is, if a team of mercenaries with a grudge doesn't get it first.

Dr. Dan Kotler—polymathic anthropologist and FBI consultant—teams with his FBI partner, Agent Roland Denzel, to investigate the murder of an archaeobiologist, hot on the trail of a source for makry ypno. All signs point to the possibility of its existence, deep within the Mojave Desert, and it's potential use by Native Americans in the region.

But Kotler and Denzel are not the only ones on the trail of this ancient drug. A team of mercenaries, led by an enemy from Kotler's past, has found the makry ypno first... and are willing to kill anyone to keep it under their control.
