Four award-winning authors. Four amazing alternate histories. In this collection of novellas, four masters of alternate history turn back time, twisting the facts with four excursions into what might have been. Bestselling author Harry Turtledove imagines a different fate for Socrates (now Sokrates); S. M. Stirling envisions life "in the wilds of a re-barbarized Texas" after asteroids strike the earth in the 19th century; Sidewise winner Mary Gentle contributes a story of love (and pigs) set in the mid-15th century, as European mercenaries prepare to sack a Gothic Carthage; and Nebula nominee Walter Jon Williams pens a tale of Nietzsche intervening in the gunfight at the O.K. Corral.

“Turtledove is the standard-bearer for alternate history.”— USA Today The novels of Harry Turtledove show history balancing on single moments: One act of folly. One poor decision. One moment of rage. In this astounding new series, the unthinkable has come to pass. The Cold War turns hot—and the United States and the Soviet Union unleash their nuclear arsenals upon each other. Millions die. Millions more are displaced. Germans battle side by side with Americans, Polish freedom fighters next to Russian fascists. The genie is out of the bottle. And there’s no telling what fresh hell will come next. At the heart of Fallout are Harry Truman and Josef Stalin. Even as Joe McCarthy rises in power, the U.S. president is focused elsewhere, planning to cut off the head of the Soviet threat by taking out Stalin. It’s a daring gambit, but the Soviets have one of their own. Meanwhile, Europe’s weak sisters, France and Italy, seem poised to choose the winning side, while China threatens to overrun Korea. With Great Britain ravaged and swaths of America in ruins, leaders are running out of options. When the United States drops another series of bombs to slow the Russian advance in Europe, Stalin strikes back—with horrifying results. These staggering events unfold through the eyes of a sprawling cast of characters: a Holocaust survivor in a displaced persons camp in Washington; the wife of a bomber pilot and her five-year-old daughter starting a new existence; a savage Soviet fighter waging war by his own rules; a British pub owner falling in love with an American pilot. In the masterly hands of Harry Turtledove, this epic chronicle of war becomes a story of human struggle. As the armies of the world implode, the next chapter will be written by the survivors—those willing to rise up for an uncertain future. Praise for Fallout “Turtledove proves, yet again, that he is the best when it comes to rewriting history!” — Suspense Magazine “Turtledove, the master of alternate history, has done well again.” — Shelf Awareness “No one writes alternate-history novels quite like Turtledove. . . . Expect epic political stakes as well as personal and heartfelt stories of war.” —BookTrib

THE CLIMACTIC CONCLUSION OF A WORLD WAR As the Derlavian War rages into its last and greatest battles, allied nations maneuver for advantage over one another in the postwar world. But before that time can come, the forces of Algarve, Unkerlant, and their allies must clash a final time, countering army with army and battle magic with ever-more-powerful battle magic. In the midst of it all, the people the war has battered and reshaped must struggle to face their greatest individual challenges, as loves are shattered and found, terrible crimes avenged...and some journeys end forever. Nor will the end of war bring lasting peace...

Usually Crosstime Traffic concerns itself with trade. Our world owns the secret of travel between parallel continuums, and we mean to use it to trade for much-needed resources with the worlds next door. Preferably without letting them know about any of that parallel-worlds stuff. But there’s one parallel world that’s different. In it, the atomic war broke out in 1967, at the height of the Summer of Love. Now, Crosstime Traffic has been given a different sort of mission: find out what on earth, or on the many earths, went wrong.
