From #1 New York Times bestselling author James Rollins, the latest riveting and suspenseful thriller in the Sigma Force series, told with his trademark blend of cutting edge science, historical mystery, and pulse-pounding action.“Rollins is one of the most inventive storytellers
writing today.”—Lincoln Child

For eons, the city of
Troy—whose legendary fall was detailed in Homer’s Iliad—was
believed to be myth, until archaeologists in the nineteenth century uncovered
its ancient walls buried beneath the sands. If Troy was real, how much of
Homer’s twin tales of gods and monsters, curses and miracles—The Iliad and The
Odyssey—could also be true and awaiting discovery?

In the frozen tundra of
Greenland, a group of modern-day researchers stumble on a shocking
find: a medieval ship buried a half-mile below the ice. The ship’s hold
contains a collection of artifacts—tools of war—dating back to the Bronze Age.
Inside the captain’s cabin is a clockwork gold map imbedded
with an intricate silver astrolabe. Once activated, the moving map traces
the path of Odysseus’s famous ship as it sailed away from Troy. But the route
detours as the map opens to reveal a fiery river leading to a hidden realm
underneath the Mediterranean Sea—the subterranean world of Tartarus, the Greek
name for Hell.

When word of Tartarus
spreads, the phantasmagoric horrors found in Homer’s tales are all too real—and
whoever possesses them can use their awesome power to control the future of
humanity.

Now, Sigma Force must prevent a tyrant from igniting a
global war and cross the very gates of Hell.
