The Resonance Awakening

Commander Corbin Dallas and his Vanguard team were supposed to make history as the first humans on Mars. Instead, they trigger an ancient artifact that violently catapults them into the crosshairs of an apocalyptic interstellar war. Outgunned and cut off from Earth, the team must scavenge what they can to survive the ruins of an alien transit network. Vanguard One has a new mission: hold the line and find a way home. But opening the door may have been humanity's fatal mistake.
