Nia Vale remembers a life she never lived.
She was told Talstra's body-transfer program lets human consciousness travel safely into a synthetic shell. Her sleeping body waits at home. Her new body serves on the Moon. And every return is supposed to prove that she is still herself.
Then Nia discovers the truth: the system does not move a person. It makes a copy, sends the copy into danger, and gives the original only the memories afterward. The girl fighting in metal is not a temporary body. She is a person with no human body to return to.
As old transit records expose a buried war among humanity, embodied machines, and the vast network called Z-Ran Echo, Nia must decide whether to save the human life she remembers - or claim the synthetic life that is undeniably her own.
