This is a very peculiar story about the horrors of interstellar flights: outer space with its impenetrable darkness is a true abode of nightmares. Monsters living in interstellar space are incomprehensible. Telepathic humans perceive them as dragons; and the People’s Partners — the great warrior cats — Captain Woof and Lady May — like giant rats. Light is the doom of these monsters. Going beyond the salvific sunlight, people doom themselves to death or insanity. Thus, interstellar flights turn into an eternal battle for survival.
