In this, Orion's Sword, Vol 3 of THE FUTURE AT WAR series, brilliant science fiction and military writers take a close look at the future of our planet in the light of History's only sure thing: The Future of War. As inevitable as the colonization of Space: invasions of earth, the solar system at war, wherever humans go, they take their conflicts with them.
