Mansions of Karma — Ruth White

A mystical soft sci-fi for older teens and adults. At an unspecified time in the future a spiritual group of Earthlings establish their utopian society on a small Goldilocks planet at the edge of the known universe. It is here on Aquarius that Lily Reynolds spends a carefree childhood among the hills, streams and meadows of this new Eden. When the colonists have completed the building of homes and a school, tragedy strikes in the form of a deadly virus. Only twelve people survive, all of them children. Lily at the age of eleven, is the oldest. With no communication to other worlds, the youngsters wait for a promised starship for rescue. But it does not come. The children turn into teenagers with a limited knowledge of adult relationships. They have only each other and a few books to guide them. In time the teens become attuned to the mystical vibrations of the planet, as the Mansions of Karma appear periodically in the sky to remind them they are not alone, but forever a part of the great universal life force. And then one day the starship actually does come, but it is not there on a rescue mission
