An extraordinary new thriller of the future from #1 New York Times-bestselling and Pulitzer Prize-winning author John Sandford and internationally-known photo-artist and science fiction aficionado Ctein. In 2066, a Caltech intern notices an anomaly - something is approaching Saturn, and decelerating. Space objects don't decelerate. Spaceships do. A flurry of meetings produces the inescapable conclusion: Whatever built that ship is at least 100 years ahead in technology, and whoever can get their hands on it will have an unmatchable advantage.
