Millions of years ago, Xenia and Yonan, a telepathic part-alien/part-human couple, happily married for four-hundred years and planned to live together forever, face unexpected death . . . in three moons. Worried their reincarnated selves wont find each other in future lives, the couple attempt astral time travel to ensure their future selves fall in love and live long human lives together--while pending doom looms closer. Journeying to prehistoric France, ancient Egypt, Tudor England, 19th century Iowa, and the present day, they make mistakes along the way while learning about the future human world. Experiencing disappointments and setbacks, they fear time will run out.
