Todd Marc

I write hard science fiction focused on small crews, corporate space, and realistic futures shaped by human decisions rather than miracles or monsters.

My stories explore what happens when ordinary people are pushed into impossible situations—where physics is unforgiving, politics are messy, and power is rarely heroic. From hidden research stations near Ganymede to solar-system-scale conflicts in the Human Space series, the stakes are always human first.

If you’re interested in grounded sci-fi, realistic space travel, and science fiction that treats technology, economics, and responsibility seriously, you’re in the right place.
