Vega awakens from cryo-sleep three centuries later. She has nothing on her except a chip called “Memories of Happiness,” on which footage of guinea pigs is recorded. In addition to the chip, Vega is tormented by migraines and a voice in her head, which appears to be the name O. Vega mistakes O for a neuromind - an upgrade from the ZASLON corporation, only O is someone completely different. And Vega herself too. Why did Vega disappear three centuries ago? What are I-people and H-machines? And what does a guinea pig have to do with it? Vega will receive all the answers as soon as she visits the ZASLON corporation, where she is invited by a colleague named Vadim, who spent three centuries in cryo sleep, like Vega, and witnessed what happened.
