A group of six people awaken in stasis pods with amnesia aboard a starship called the Raza. They have no memories of their identities or their lives before awakening, so they assume the names One through Six, in the order in which they left stasis. They stabilize their vessel and set about trying to determine who they are and what happened to them. Facing threats at every turn, they have to work together to survive a voyage charged with vengeance, betrayal and hidden secrets.
