“[Rollins] is what you might end up with if you tossed Michael Crichton and Dan Brown into a particle accelerator together.”—New York Times Book ReviewArriving home on Christmas Eve, Commander Gray Pierce discovers his house ransacked, his pregnant lover missing, and his best friend’s wife, Kat, unconscious on the kitchen floor. With no shred of evidence to follow, his one hope to find the woman he loves and his unborn child is Kat, the only witness to what happened. But the injured woman is in a semi-comatose state and cannot speak—until a brilliant neurologist offers a radical approach to “unlock” her mind long enough to ask a few questions.What Pierce learns from Kat sets Sigma Force on a frantic quest for answers that are connected to mysteries reaching back to the Spanish Inquisition and to one of the most reviled and blood-soaked books in human history—a Medieval text known as the Malleus Maleficarum, the Hammer of Witches. What they uncover hidden deep in the past will reveal a frightening truth in the present and a future on the brink of annihilation, and force them to confront the ultimate question: What does it mean to have a soul?“When it comes to the blending of action, adventure, history, and science, there is no other author who does it better than Rollins.”—Booklist

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.“[Rollins] is what you might end up with if you tossed Michael Crichton and Dan Brown into a particle accelerator together.”—New York Times Book Review
