Europeans once called the Americas a New World, a months-long voyage away. What might they have thought of a two-thousand year voyage to Epsilon Eridani, one hundred trillion kilometres distant, a true new world?

Let’s call home. But an astonishing discovery makes these people think again. We have lived in Paradise for two thousand peaceful, productive, happy years in our small green city states of Space. We have become innocents on our long voyage and the people of Earth, when last heard of, long ago, were again in violent contention. Can we resist them if their influence is now malign? With Paradise regained, can it once more be lost?
