Old Guns: A Military Sci-Fi Adventure

When the Colonial Shield Federation confronts an ancient alien threat, they turn to the only two Marines who survived first contact: Frank Cage and Martin Kelvin. After a decade of coping with their past in very different ways, their quiet retirement is shattered by a military transport that brings grim orders and unexpected consequences. Donning outdated power armor again, they must team up with combat-tested scientists to face the malevolent Hollow, who collect rather than kill. This gripping start to a military sci-fi saga showcases the challenges these veterans face as they navigate survival and the heavy costs that come with it.
