The year is 3347. The 351st marine detachment is being deployed on Azora to help the Interstellar Alliance forces on-planet to defend against the Riesman Confederation onslaught. Azora is a chain of urban sprawls with few military installations. Confederation forces have taken control of much of the planet, but pockets of resistance have cropped up in several major cities. The remnants of the planetary National Guard, as well as Alliance military units are putting up a good fight, but they are severely outmanned and outgunned.
The story is set in an alternate universe, in the 3350’s, amidst an Interstellar War and revolves around the lead character, Major Ryan Lewis, and the unraveling of a plot by his Commanding Officer, Colonel Edward Ross, and his best friend and squad mate, Captain Colin Maddox.
