Kurt Austin is mid-mission when his new colleague, the stunning archeologist Skye Labelle, is called away to examine a mysterious 16th-century military helmet discovered in the possession of a very contemporary-looking corpse. Ms. Labelleβs research on the armor draws her into the sights of a ruthless black-widow with her own plans for the artifact. As danger creeps closer to Ms. Labelle, a scientist half-way across the globe is kidnapped. At the same time, experts working to harvest an enzyme discovered two thousand feet down in the North Atlantic, in an area known as βLost City,β start turning up dead. Worlds apart in location and areas of expertise, they all have something in common. And itβs up to Kurt Austin, with the help of Joe Zavala and the NUMA Special Assignments Team, to put the pieces together if heβs going to keep his friend safe.
