Earth Thought It Was Alone.
It Was Wrong.

Humanity spent centuries searching the stars for signs of life. We built stations, launched probes, and listened for signals in the dark. We were patient. We were optimistic. We were completely unprepared.

When first contact finally came, it didn't arrive with greetings. It arrived over Luna Station — with weapons that made our best military technology look like harsh language, in the middle of a war between alien species that had forgotten we existed.

Captain Michael Denton didn't ask to be at the center of it. But the universe doesn't ask permission.

Earth Unbound is a military sci-fi series rooted in real service, real tactics, and a universe being built one book at a time. Multiple alien species. Ancient technology. An AI that thinks faster than command can order. And a captain who has everything to lose.
