The year is 2052, and the human race is still struggling to recover from a massive pandemic flu some 40 years previously. When an independent prospector on Saturn’s moon Titan discovers an alien artifact, assumptions that we are alone in the universe are called into question. Knowing that news of such a discovery could prompt chaos on Earth, a small team is sent to investigate and hopefully manage the situation. What they find is that there's more to human history, and human abilities, than any of them ever imagined. And that they will need all those insights, and all those abilities, to face the greatest threat yet to human survival.
