Escaping an Earth ravaged by economic collapse, the colony ship Deepstar soars toward a dazzling odyssey of alien contact. Near Neptune, the crew sights the rogue planet Iris approaching our solar system, and decides to settle on one of its moons. But on their strange new home's crater-marked landscape, they discover the Artifact: an ancient extraterrestrial spacecraft that is deserted, but still operable-and only the first step on a dizzying journey through both inner and outer space. A stunning glimpse into not only a gritty, hard-edged future, but also an ancient alien civiliza-tion, Iris follows the Deepstar crew on a challenging and unforgettable adventure of emotional and extraterrestrial exploration.
