Jane Psmith confesses a weakness for a certain kind of speculative fiction and recommends some works in that field. The three here are also among my favourites, so I can comfortably agree with the choices:

As I’ve written before, I am an absolute sucker for alternate history. Unfortunately, though, most of it is not very good, even by the standards of genre fiction’s transparent prose. Its attraction is really the idea, with all its surprising facets, and means the best examples are typically the ones where the idea is so good — the unexpected ramifications so startling at the moment but so obvious in retrospect — that you can forgive the cardboard characters and lackluster prose.

But, what the heck, I’m feeling self-indulgent, so here are some of my favorites.

• Island in the Sea of Time et seq., by S.M. Stirling: This is my very favorite. The premise is quite simple: the island of Nantucket is inexplicably sent back in time to 1250 BC. Luckily, a Coast Guard sailing ship happens to be visiting, so they’re able to sail to Britain and trade for grain to survive the winter while they bootstrap industrial civilization on the thinly-inhabited coast of North America. Of course, it’s not that simple: the inhabitants of the Bronze Age have obvious and remarkably plausible reactions to the sudden appearance of strangers with superior technology, a renegade sailor steals one of the Nantucketers’ ships and sets off to carve his own empire from the past, and the Americans are thrust into Bronze Age geopolitics as they attempt to thwart him. The “good guys” are frankly pretty boring, in a late 90s multicultural neoliberal kind of way — the captain of the Coast Guard ship is a black lesbian and you can practically see Stirling clapping himself on the back for Representation — but the villainous Coast Guardsmen and (especially) the natives of 1250 BC get a far more complex and interesting portrayal.¹ Two of them are particularly well-drawn: a fictional trader of the thinly attested Iberian city-state of Tartessos, and an Achaean nobleman named Odikweos, both of whom are thoroughly understandable and sympathetic while remaining distinctly unmodern. The Nantucketers, with their technological innovations and American values, provide plenty of contrast, but Stirling is really at his best in using them to highlight the alien past.
• Lest Darkness Fall, by L. Sprague de Camp: An absolute classic of the genre. I may not love what de Camp did with Conan, but the man could write! One of the great things about old books (this one is from 1939) is that they don’t waste time on technobabble to justify the silly parts: about two pages into the story, American archaeologist Martin Padway is struck by lightning while visiting Rome and transported back in time to 535 AD. How? Shut up, that’s how, and instead pay attention as Padway introduces distilled liquor, double-entry bookkeeping, yellow journalism, and the telegraph before taking advantage of his encyclopedic knowledge of Procopius’s De Bello Gothico to stabilize and defend the Italo-Gothic kingdom, wrest Belisarius’s loyalty away from Justinian, and entirely forestall the Dark Ages. If this sounds an awful lot like the imaginary book I described in my review of The Knowledge: yes. The combination of high agency history rerouting and total worldview disconnect — there’s a very funny barfight about Christology early on, and later some severe culture clash that interferes with a royal marriage — is charming. Also, this was the book that inspired Harry Turtledove not only to become an alt-history writer but to get a Ph.D. in Byzantine history.

• Ruled Britannia, by Harry Turtledove: Turtledove is by far the most famous and successful alternate history author out there, with lots of short pieces and novels ranging from “Byzantine intrigue in a world where Islam never existed” (Agent of Byzantium) to “time-travelling neo-Nazis bring AK-47s to the Confederacy” (The Guns of the South), but this is the only one of his books I’ve ever been tempted to re-read. The jumping-off point, “the Spanish Armada succeeded”, is fairly common for the genre² — the pretty good Times Without Number and the lousy Pavane (hey, did you know the Church hates and fears technology?!) both start from there — but Turtledove fasts forward only a decade to show us William Shakespeare at the fulcrum of history. A loyalist faction (starring real life Elizabethan intriguers like Nicholas Skeres) wants him to write a play about Boudicca to inflame the population to free Queen Elizabeth from her imprisonment in the Tower of London, while the Spanish authorities (represented, hilariously, by playwright manqué Lope de Vega) want him to write one glorifying the late Philip II and the conquest of England. Turtledove does a surprisingly good job inventing new Shakespeare plays from snippets of real ones and from John Fletcher’s 1613 Bonduca, but of course I’m most taken by his rendition of the Tudor world. Maybe I should check out some of his straight historical fiction …

1. Well, except for the peaceful matriarchal Marija Gimbutas-y “Earth People” being displaced from Britain by the invading Proto-Celts; they’re also “good guys” and therefore, sadly, boring.

2. Not as common as “the Nazis won”, obviously.

I agree with Jane about Island in the Sea of Time, but my son and daughter-in-law strongly preferred the other series Stirling wrote from the same start point: what happened to the world left behind when Nantucket Island got scooped out of our timeline and dumped back into the pre-collapse Bronze Age. Whereas ISOT has minimal supernatural elements to the story, the “Emberverse” series beginning with Dies the Fire went on for many, many more books and had much more witchy woo-woo stuff front-and-centre rather than marginal and de-emphasized.

While I quite enjoyed Ruled Britannia, it was the first Turtledove series I encountered that I’ve gone back to re-read: The Lost Legion … well, the first four books, anyway. He wrote several more books in that same world, but having wrapped up the storyline for the Legion’s main characters, I didn’t find the others as interesting.
