Seven Deadly Sons (Stone Soldiers #7) - Stone Soldiers, #7

A new breed of werewolf has come to Miami, murdering retired Nazi Hunters. Bigger, stronger, and faster than any werewolf ever seen, these mysterious creatures seem to be capable of striking any point on the globe at will. To prevent further deaths, America's super soldiers will have to track the monsters to a long-forgotten German base in Antarctica and unravel an ancient mystery buried beneath the polar ice.
The Stone Soldiers are America's secret weapon against the forces of darkness. A small detachment of psychics, supernatural soldiers and men turned to living stone, they respond to threats conventional forces cannot face. Battling myths, monsters and legends around the world, the men and women of Detachment 1039 stand ready to do whatever it takes to stop evil in its tracks.
