A consortium of planets sends a philosopher and an interstellar crew to Earth.
Upon coming close to their destination, they find the planet is protected by something left behind from Earth’s original ancient inhabitants - a charge that sends the crew’s transdimensional ship out of time. Their ship crash-lands on Earth, but a long time ago. And as they nearly get it going again, they fail to account for everything in the temporal disruption: there is a terrible accident. The crew is separated and scattered through time.
This is the story of how they find each other again and make sense of a civilization that confounds them.
