Past, present, and future Brazil, with all its color, passion, and shifting realities, come together in a novel that is part SF, part history, part mystery, and entirely enthralling.Three separate stories follow three main characters:--Edson is a self-made talent impressario one step up from the slums in a near future São Paulo of astonishing riches and poverty.

And if that means Galileo must be burned at the stake, so be it.From Galileo's heresy trial to the politics of far-future Jupiter, Kim Stanley Robinson illuminates the parallels between a distant past and an even more remote future—in the process celebrating the human spirit and calling into question the convenient truths of our own moment in time.

    But they also found themselves up against creatures who considered humans mere cattle to sacrifice!

    You will learn and grow and strive to be excellent." Created as an experiment by the time-traveling goddess Pallas Athene, the Just City is a planned community, populated by over ten thousand children and a few hundred adult teachers from all eras of history, along with some handy robots from the far human future--all set down together on a Mediterranean island in the distant past.The student Simmea, born an Egyptian farmer's daughter sometime between 500 and 1000 A.D, is a brilliant child, eager for knowledge, ready to strive to be her best self. The teacher Maia was once Ethel, a young Victorian lady of much learning and few prospects, who prayed to Pallas Athene in an unguarded moment during a trip to Rome--and, in an instant, found herself in the Just City with grey-eyed Athene standing unmistakably before her.Meanwhile, Apollo--stunned by the realization that there are things mortals understand better than he does--has arranged to live a human life, and has come to the City as one of the children. He knows his true identity, and conceals it from his peers. For this lifetime, he is prone to all the troubles of being human.Then, a few years in, Sokrates arrives--the same Sokrates recorded by Plato himself--to ask all the troublesome questions you would expect. What happens next is a tale only the brilliant Jo Walton could tell.

    What exists has been carved out amidst a war between two rival factions: the Line, paving the world with industry and claiming its residents as slaves; and the Gun, a cult of terror and violence that cripples the population with fear. The only hope at stopping them has seemingly disappeared--the Red Republic that once battled the Gun and the Line, and almost won. Now they're just a myth, a bedtime story parents tell their children, of hope. To the west lies a vast, uncharted world, inhabited only by the legends of the immortal and powerful Hill People, who live at one with the earth and its elements. Liv Alverhyusen, a doctor of the new science of psychology, travels to the edge of the made world to a spiritually protected mental institution in order to study the minds of those broken by the Gun and the Line. In its rooms lies an old general of the Red Republic, a man whose shattered mind just may hold the secret to stopping the Gun and the Line. And either side will do anything to understand how.

    At least that was the theory American scientists were exploring in an effort to explain the new sources of knowledge the Russians possessed. Perhaps Russian scientists had discovered how to transport themselves back in time in order to learn long-forgotten secrets of the past. That was why young Ross Murdock, above average in intelligence but a belligerently independent nonconformist, found himself on a "hush-hush" government project at a secret base in the Arctic. The very qualities that made him a menace in civilized society were valuable traits in a man who must successfully act the part of a merchant trader of the Beaker people during the Bronze Age.For once they were transferred by time machine to the remote Baltic region where the Russian post was located, Ross and his partner Ashe were swept into a fantastic action-filled adventure involving Russians, superstitious prehistoric men, and the aliens of a lost galactic civilization that demanded every ounce of courage the Americans possessed.Approx. 7 hours
