The colony ship Ragtime docks in the Lagos system, having travelled light years from home to bring one thousand sleeping souls to safety among the stars. Some of the sleepers, however, will never wake - and a profound and sinister mystery unfolds aboard the gigantic vessel. Its skeleton crew are forced to make decisions that will have repercussions for all of humanity's settlements - from the scheming politicians of Lagos station, to the colony planet of Bloodroot, to other far flung systems and indeed Earth itself. Arthur C. Clarke Award winner Tade Thompson makes a triumphant return to science fiction with this unforgettable vision of humanity's future in the chilling emptiness of space.
