When the Ares I mission vanishes mid-flight-leaving behind an intact spacecraft but no crew-the explanation is simple at first: catastrophic failure. It isn't. As scientists investigate, a pattern emerges. Probes pass through a certain point in space without incident. Signals cross it. Machines survive it. Humans do not. What lies beyond Earth is not empty-and something is preventing humanity from leaving. As the world turns inward and ambition quietly collapses, physicist Aris Thorne searches for an explanation that refuses to exist. Meanwhile, industrialist Kaelen Vane prepares a more dangerous response: to force whatever is out there to answer. But when reality itself begins to shift-memories falter, events repeat, and people are erased without a trace-it becomes clear that the boundary is not just a limit. It is a system. And humanity may already be inside it.
