Tom Bartlett signs on as a starship crewman while his telepathic twin brother stays behind on Earth, providing instant communication across light‑years. As relativity stretches years into decades, the twins struggle with the changing meaning of family and home.

As a final exam in survival, students are teleported to a distant wilderness world for a short test—then the gate fails to reopen. Stranded, they must build a society from scratch while fending off predators, politics, and the fear of never going home.
