Battle Line — Billy Bennett

The year is 2120 A.D. The Terran System has been invaded by the most ruthless conquerors in the galaxy. After being routed in two major engagements in the outer Solar System, veteran ace Lieutenant Jack Thunder and his fellow Star Sword pilots and Space Marines must hold the line on the planet Mars, as the Zidian armada attacks, and an army of battle mechas are landed to conquer the colony. While the invaders prepare to field the ultimate secret weapon, and another mysterious alien race sits on the side lines, debating whether to enter the conflict or leave the Earth to its doom, Jack Thunder, April Kelley, and the rest of Humanity's greatest heroes are thrown into a maelstrom of love, war, and tragedy as they fight against all odds to win the victory.
