The final volume of a trilogy that began with Red Mars and continued with Green Mars, Blue Mars completes the story of the "First Hundred", a pioneering group of explorers who have overseen a terraforming project that transformed Mars from a lifeless planet into a world habitable by humans. An anti-ageing breakthrough has kept the First Hundred alive for three centuries and in that time, their motives, desires and passions have evolved in ways that parallel the changes on Mars itself. Conceptually complex and daring, the publication of Blue Mars marks the completion of a modern science fiction masterpiece.

Kim Stanley Robinson, justly famous for his science fiction, has created a mesmerizing fantasy work in A Short, Sharp Shock. Each brief chapter (with evocative titles such as "Beauty Is the Promise of Happiness") explores a little further along the path of the amnesiac protagonist, Thel. Thel finds himself on an amazing world, which has just one narrow ridge of land encircling the globe, with endless ocean on either side. And Thel is on a quest, searching for the woman who was with him when he first awakened, but who was taken by the murderous spine kings. In his travels along the ribbon of land, Thel encounters exotic local peoples and their legends of the origin of the world, and learns more about his companions and himself. Robinson's imagination is far-ranging and he has a pointed way with words: in a scene where Thel is slowly pushed through a magical mirror, Robinson's evocation of pain is unforgettable. A Short, Sharp Shock is guaranteed to haunt the reader for a long time. —Blaise Selby

In the near future Wade Norton has been sent to Antarctica by Senator Phil Chase to investigate rumours of environmental sabotage. He arrives on the frozen continent and immediately begins making contact with the various scientific and political factions that comprise Antarctic society. What he finds is an interesting and diverse mix of inhabitants who don't always mesh well but who all share a common love of Antarctica and a fierce devotion to their life there. He also begins to uncover layers of Antarctic culture that have been kept hidden from the rest of the world, some of which are dangerous indeed. Events are brought to a head when the saboteurs—or "ecoteurs" as they call themselves—launch an attack designed to drive humans off the face of Antarctica. This is Kim Stanley Robinson's first book since his award-winning Mars trilogy, and while some of the themes may be familiar to seasoned Robinson readers the book is never less than engrossing. As usual Robinson does a masterful job with the setting of his story, and anyone interested in Antarctica won't want to miss this one. —Craig Engler, Amazon.com

The Martians is a collection of stories, alternate histories, poems and even the complete text of a planetary constitution based on Kim Stanley Robinson's award-winning Mars trilogy (composed of Red Mars, Green Mars, and Blue Mars). For those unfamiliar with the series, The Martians from the title are the humans who have colonised and terraformed the Red Planet over the course of several generations. While Robinson told their story at considerable length in his novels, The Martians fleshes out some of his more interesting characters and also adds depth to their world.

When it's at its best, this collection presents stand-alone stories of life, love and work on our celestial neighbour, ranging from the tale of an expedition seeking to conquer Olympus Monsin in "Green Mars" to a folksy story of friendship and baseball in "Arthur Sternbach Brings the Curveball to Mars". Unfortunately, some of the material here can be tough going for those unfamiliar with Robinson's Mars milieu. For instance, the ending piece, "Purple Mars", is apparently an autobiographical snippet about the day Robinson finished writing the final novel. That's great stuff for someone who has been following the entire Mars saga from beginning to end, but newcomers will probably not know what to make of it.

Still, there is enough material here to interest anyone on the lookout for some good Mars stories. Although Robinson has made his name by writing fat novels that span dozens of generations and characters, in The Martians he proves that he is also adept at shorter pieces. It's a fine if somewhat uneven collection that serves to round off the Mars universe while providing some excellent reading. —Craig E. Engler

Kim Stanley Robinson's ambitious exploration of alternative history in The Years of Rice and Salt poses the daunting question "How would our world have developed without Europe?" (Or, rather, without European culture?) When the scouts of the Mongol leader Temur the Lame (Tamburlaine) enter Hungary in 1405, they find only emptiness and death. Plague has swept Europe off the gameboard of history.

The centuries that follow are initially dominated by expanding Islamic nations and the monolithic Chinese empire. It's a grand chronicle of rising and falling cultures, with individuals forever struggling to make a difference to the slow-motion landslide of events. Extra continuity is given by a touch of fantasy as the Buddhist wheel of reincarnation brings back the same characters (coded by initials) again and again with varied roles, relations and sexes. Their stories are touching and very human.

Episodes of our own history are artfully echoed. America is discovered by Chinese ships from the west, with fateful effects for the native tribes and the "Inka" theocracy further south. The scientific ideas of da Vinci's Renaissance are reflected by the Alchemist of Samarkand, reluctantly devising fresh weapons of war. New forms of government arise. Islamic splinter groups move into empty Europe and in that softer climate develop dangerous notions like feminism. A First World War eventually comes, later than we'd expect but horribly prolonged.

Then Muslim scientists begin to see the implications of the mass-energy theories of a savant from the Indian subcontinent:

Invisible worlds, full of energy and power: sub-atomic harems, each pulsing on the edge of a great explosion...There was no escaping the latent violence at the heart of things. Even the stones were mortal.

This immense tapestry of history that never happened is constantly illuminated by the small comedies, tragedies, romances and triumphs of memorably real individuals. The Years of Rice and Salt is a brave new landmark in alternate history, deservedly shortlisted for the British SF Association and Arthur C Clarke awards. —David Langford
