Gnosia

Yuuri wakes aboard a spacecraft with no memory of how she got there. The crew has a more immediate problem: someone among them is Gnosia, an inhuman enemy that looks perfectly human and kills while the ship is in warp. With no reliable way to identify the infiltrator, everyone must debate, accuse, and vote one suspect into cold sleep each day.

The system fails, Yuuri dies, and then she wakes at the beginning again. Each loop changes the number of crew members, their roles, and even who can be trusted. To escape, Yuuri must learn the people around her, expose the Gnosia, and uncover why time itself refuses to let the crisis end.
