The Sigma Force novels follow a secret team of operatives working under DARPA, the Pentagon’s research arm. Each member is chosen for a rare mix of scientific brilliance and battlefield skill. Their assignments take them around the globe, where they race to uncover and protect discoveries that could change history, from lost technologies to ancient mysteries. In every book, the stakes are the same: if these finds fall into the wrong hands, the safety of the United States and the wider world is on the line.
