Epic Science Fiction In the 22nd century, humanity has ventured to the stars. Yet alien races, fractious colonies, contending governments and aberrant mutations all vie for supremacy amid the wonders of this new age. At the center of the conflict stands a new breed of humans — men and women with psychic powers — whose actions will determine humanity’s ultimate fate.
