Far in the future, an interplanetary civil conflict has ground to an uneasy halt, leaving its human victims bitter and desperate: Kithri, the daughter of a scientist, abandoned on a desolate mining planet with no hope to use her talents, and Eril, shell-shocked pilot, finding adapting to peace more difficult than he dreamed. A freak accident sends them back to a time when their desert world was lush and green, when an alien civilization stands on the brink of a war of total destruction. Unexpectedly linked with Lennart, a spaceman from an earlier era in galactic history, and Brianna, an anthropologist from an alternate universe, they must choose to remain outside the conflict or to stand up for what they believe, even at the cost of never getting home again
