Books that imagine that history took a different course

THEY MAY not have the cachet of the Pulitzer or the Booker, but the Sidewise Awards for Alternate History deserve respect.

The what-if genre of fiction is growing fast, with work of startling quality and originality. Take the last Sidewise long-form winner, “Cahokia Jazz” by Francis Spufford. A noir thriller that takes place in the 1920s, it imagines an America in which the native population had not been nearly wiped out by smallpox. Other winners of the 29-year-old prize include Laurent Binet's “Civilizations”, which imagines that the Incas invaded Europe in 1531, 39 years after Christopher Columbus did not discover the Americas. Tweaking history is surely as much fun as a novelist can have: losers become winners, and not quite everything changes. What if General Lee had won at Gettysburg? What if Napoleon had seen off Wellington and Blticher at Waterloo? The Nazis are overrepresented on alternate-history bookshelves as they are in other sections of most libraries. “The Plot Against America” by Philip Roth, for example, places Charles Lindbergh, a suspected Nazi sympathiser, in the White House. Not far behind is John F. Kennedy, who skipped that visit to Dallas, or perhaps fell victim to the mafia/Cubans/Russians/Lyndon Johnson. As this selection of the best alternate-history novels demonstrates, the world of imagined pasts is rich and potentially endless.
