One ship, Probe 19, could restart life on Earth. They had searched for thousands of years; and they had found it. However, it wasn't one ship, it was nineteen. On the Dark Satellite, beyond Neptune, they worked to copy the life they had found, to make lifespaces to hold it. To grow it.But they weren't returning to Earth. They were leaving.Nineteen starships, spiral lifespaces containing facsimile strips of Earth within were heading out of the Solar System. Scientists had conquered sleep and extended human lifespans. Could they find new homes? Could they survive the deep black of the universe? None of them knew their destinations, but they had the Svalbard life data, human embryos, and fifteen thousand living dreamers.And they had a chance. Humankind had nineteen chances.
