After the death of J. D. Sauvage's friend and guide Nemo, the alien squidmoth, she and the first contact crew of the Earth ship <i>Starfarer</i> hope that the enigmatic being's legacy - the starship <i>Nautilus</i> - will lead them closer to communication with alien intelligence. Awaiting them on their journey are the representatives of the Four Worlds and one last chance to join the interstellar Civilization, from which Earth has long been barred.
<br>But first J. D. and her fellow wayfarers must convince the aliens that humanity is worthy of Civilization. It is an argument they will find hard to win, given humanity's violent past. What's worse, they don't have much time to win it. For the cosmic string that can guide the <i>Starfarer</i> home is fast unraveling. Soon the beleaguered crew will have to make a decision that will affect all the people of Earth: whether to turn back to Earth while there's still time - or make one last desperate effort to win over their implacable alien hosts.
