A violently insane woman who believes that she is Catherine the Great is on a spaceship with her brother and two sisters. Rather than take her to an asylum, they are taking her to an asteroid. It has been discovered that the asteroids are inhabited, self-contained worlds with unique populations and cultures, each of which perfectly complements the manifestations of individuals’ unique or not-so-unique insanities. She is being taken to a world where she CAN be Catherine the Great and the inhabitants will accept her as such.
