In the race to save one of their own, Sigma Force must wrestle with the deepest spiritual mysteries of mankind in this mind-expanding adventure from the #1 New York Times bestselling author, told with his trademark blend of cutting-edge science, historical mystery, and pulse-pounding action.Arriving 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?

While not yet confirmed, there are rumors that this could be a two-book year for Rollins, similar to what he did in the past when he released his first two Tucker Kane spin-off books (The Kill Switch and War Hawk), which he co-wrote with author Grant Blackwood, in addition to a new Sigma Force book. As of right now, that’s all speculation, but we’ll update this article once we know for sure.

In the meantime, The Hammer of Witches is available for pre-order wherever books are sold.
