My ambition for "First Contact Chaos" began simply enough: two alien science vessels arrive, setting the stage for the eventual "lights out" for our entire galaxy. It took four books to achieve that galactic blackout, but "The War of the Worlds" and "Forbidden Planet" were my guiding lights.

That approach helped me keep all four books grounded in hard science. While I didn't plunge the galaxy into darkness in ...
