O link Wikis postado nos comentários me levou ao livro The Starlight Crystal . Embora eu não consiga encontrar uma sinopse respeitável de qualquer detalhe, eu encontrei um aqui que, esperamos, vai te ajudar. Para sua conveniência, também copiei abaixo (passe o mouse sobre a área cinza para revelar o texto).
The Starlight Crystal is about a women named Paige Christian. She meets a guy named Tem and they fall in love but she has to leave to go into space on the spaceship "Traveller". The ship is made to travell so fast that one hour is equall to 10 years on Earth. Her father is the captain otherwise she would not go. The purpose of the trip is to watch mankind develop new things over the period of 2 million years. During the journey about 30 years in the Earth is destroyed by aliens. They then board the Traveller and her father is killed trying to destroy the ship. A alien helps them escape and then the creator helps them return to whats left of Earth. As they are returning she touches an alien and all her knowledge is passed to her. When they return the creator tells her to then steal the ship and drive to the end of the universe. She does then creation starts all over again. When she returns to Earth the Traveller is just leaving and she relises that she is a clone of herself. She then finds Tem and marries him. They have two children (although she never told Tem they're clones of themselves). After a while she relises that the aliens should soon attack them so using her supperior knowledge of spacecraft thanks to the alien she helps NASA build a spaceship that can freeze people and wake them up later. They launch the ship and while they are getting into the freezers she programs Tems to kill him. Then she programs hers to wake her up earlier that everyone else. When she wakes up she tells her children the fate of the Earth and tells them how to kill the aliens and where to find them. Then she kills herself. Her childen go and kill the alien but Tem Jr. was killed during the attack. Paige Jr. survived and lived happily ever after.
