2025

When a shapeshifting enemy known as Gnosia infiltrates a lone spaceship, the crew has only one way to survive: identify the imposter each day and put them into cryo-sleep. But for Yuri, the day never ends. Trapped in a time loop, she relives the first day of the crisis over and over. To escape, Yuri must uncover the truth behind Gnosia and the time loop itself—before it’s too late.
