In my time spent exploring alternate-history fiction , I’ve come to the (no doubt entirely unoriginal) conclusion that there are two different types of publications in the genre; two broad “spheres” that nestle comfortably at either end of the genre and only occasionally overlap.

The first can perhaps be best described as “traditional” fiction, i.e. those novels and anthologies that are focused on plot and atmosphere and character development — whether they be an alternate-history crime thriller (In the Case Where Your Saviors Hide), legal thriller (Defying Conventions), naval-focused military history anthology (Those in Peril) or even espionage and politics (the classic Agent Lavender).

The second sphere consists of what its authors, editors and often readers seem to prefer labelling as “counterfactual” titles, far more formal and rigid essay-style counterfactual publications that focus exclusively on cause-and-effect explorations of a change or changes in a historical scenario. Almost inevitably these are military history-focused, with titles either following the what-if format or “X Victorious”, where X can stand for, variously, the Third Reich, Dixie, the Rising Sun and other nations or entities in history.

Both spheres have their pros and cons, and until very recently I had limited myself to reviewing titles in the traditional fiction sphere, as there were so many that I had discovered while wading my way through Kindle listings and social media posts. However, in my teenage years I had been an avid reader of counterfactual military history collections, and I still have a certain fondness for them. So when I discovered that Greenhill Books and Frontline books — the main publishers of many counterfactual collections — had significantly reduced the prices of many of their titles in ebook format, it seemed like the ideal time to dive back into that sphere.

Ideas are cheap. Most people can come up with a thousand concepts for books. The skill is in the execution. In bringing that vision into life, putting the idea into words. And yet there is still a value in a good concept. There are hundreds of well-written, well-executed books that hold no interest to me because the concept is one I don’t care for. The world’s best-written story about the innate eroticism of painting walls is still unlikely to become a bestseller.

Alternate history is no different in this than other genres. For alternate-history books, often the selling point is the concept rather than the writer. Thus a question to be asked when considering writing alternate-history fiction is often less, “Is this a plausible alternate world?” and more, “Is this an interesting alternate world? Can I say something interesting about our society with this setting?” An eye-popping setting or point of departure can immediately attract the eye.

A useful weapon for that, of course, is novelty. There are a lot of alternate-history books working with World War II or the American Civil war, but other areas are less explored. There have not been many alternate-history stories written about the Anglo-Zulu War of 1879 and so, as someone who has written an article about that war, the concept of this book immediately appealed.
