Without Mirror

Humanity looked at the sky and found it empty. Six species catalogued across all of deep-space exploration. Three living, three dead. None made it far enough to leave their own world. John's crew maps the edges of the known, cataloguing what the universe left behind. Most of it is rock and silence. The rare finds are worse. In a system that should have been empty, they find something that puts humanity in a scale it was not prepared for.
A philosophical science fiction novel about what mind is, and where the threshold lies between something and someone.
