A consortium of planets sends a philosopher and an interstellar crew to blow up the 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.
