Warzone: Nemesis by Morris E. Graham

The space race was a lie, and the cold war wasn’t as cold as you thought. While we were playing spy versus spy, conducting an arms race and a space race on Earth, things were heating up in the solar system.

In 1959, an alien vessel crashed on the Navajo reservation and ushered forth a colonial space race in the solar system between the two superpowers. The prize is the mysterious metal known only as alloy-x and the alien technology that promises to make one nation or the other the dominant superpower in the arms race. The American commander finds himself fighting with the toughest antagonist of his career. He has finally met his nemesis. The stakes are high. Losing the struggle could tip the balance of power on the Earth, giving the Soviets the advantage in Earth’s cold war.
