The Crack in Space


Philip K. Dick - 1966
    Jim Briskin, campaigning to be the first black president of the United States, thinks alter-Earth is the solution to the chronic overpopulation that has seventy million people cryogenically frozen; Tito Cravelli, a shadowy private detective, wants to know why Dr Lurton Sands is hiding his mistress on the planet; billionaire mutant George Walt wants to make the empty world all his own. But when the other earth turns out to be inhabited, everything changes.Winner of both the Hugo and John W. Campbell awards for best novel, widely regarded as the premiere science fiction writer of his day, and the object of cult-like adoration from his legions of fans, Philip K. Dick has come to be seen in a literary light that defies classification in much the same way as Borges and Calvino. With breathtaking insight, he utilizes vividly unfamiliar worlds to evoke the hauntingly and hilariously familiar in our society and ourselves.

The High Crusade

Ah, but this time it's no mere primitives the Wersgorix seek to enslave; they've launched their invasion against free Englishmen! In the end, only one alien is left alive; and Sir Roger's grand vision is born. He intends for the creature to fly the ship first to France to aid his King, then on to the Holy Land to vanquish the infidel. Unfortunately, he has not allowed for the treachery of the alien pilot, who instead takes the craft to his home planet, where, he thinks, these upstart barbarians will have no choice but to surrender. But that knavish alien little understands the indomitable will and clever resourcefulness of Englishmen, no matter how great the odds against them. . .

The Family Trade


Charles Stross - 2004
    She's a successful reporter for a hi-tech magazine in Boston, making good money doing what she loves. When her researcher brings her iron-clad evidence of a money-laundering scheme, Miriam thinks she's found the story of the year. But when she takes it to her editor, she's fired on the spot and gets a death threat from the criminals she has uncovered.Before the day is over, she's received a locket left by the mother she never knew-the mother who was murdered when she was an infant. Within is a knotwork pattern, which has a hypnotic effect on her. Before she knows it, she's transported herself to a parallel Earth, a world where knights on horseback chase their prey with automatic weapons, and where world-skipping assassins lurk just on the other side of reality - a world where her true family runs things.The six families of the Clan rule the kingdom of Gruinmarkt from behind the scenes, a mixture of nobility and criminal conspirators whose power to walk between the worlds makes them rich in both. Braids of family loyalty and intermarriage provide a fragile guarantee of peace, but a recently-ended civil war has left the families shaken and suspicious.Taken in by her mother's people, she becomes the star of the story of the century-as Cinderella without a fairy godmother. As her mother's heir, Miriam is hailed as the prodigal countess Helge Thorold-Hjorth, and feted and feasted. Caught up in schemes and plots centuries in the making, Miriam is surrounded by unlikely allies, forbidden loves, lethal contraband, and, most dangerous of all, her family. Her unexpected return will supercede the claims of other clan members to her mother's fortune and power, and whoever killed her mother will be happy to see her dead, too.Behind all this lie deeper secrets still, which threaten everyone and everything she has ever known. Patterns of deception and interlocking lies, as intricate as the knotwork between the universes. But Miriam is no one's pawn, and is determined to conquer her new home on her own terms.Blending the creativity and humor of Roger Zelazny, the adventure of H. Beam Piper and Philip Jose Farmer, and the rigor and scope of a science-fiction writer on the grandest scale, Charles Stross has set a new standard for fantasy epics.

Weapons of Choice


John Birmingham - 2004
    . . . The impossible has spawned the unthinkable. A military experiment in the year 2021 has thrust an American-led multinational armada back to 1942, right into the middle of the U.S. naval task force speeding toward Midway Atoll—and what was to be the most spectacular U.S. triumph of the entire war. Thousands died in the chaos, but the ripples had only begun. For these veterans of Pearl Harbor—led by Admirals Nimitz, Halsey, and Spruance—have never seen a helicopter, or a satellite link, or a nuclear weapon. And they’ve never encountered an African American colonel or a British naval commander who was a woman and half-Pakistani. While they embrace the armada’s awesome firepower, they may find the twenty-first century sailors themselves far from acceptable.Initial jubilation at news the Allies would win the war is quickly doused by the chilling realization that the time travelers themselves—by their very presence—have rendered history null and void. Celebration turns to dread when the possibility arises that other elements of the twenty-first century task force may have also made the trip—and might now be aiding Yamamoto and the Japanese.What happens next is anybody’s guess—and everybody’s nightmare. . . .From the Trade Paperback edition.
