In 1840, Edward Oxford drew a succession of pistols and successfully assassinated the Queen of England at the time period, Queen Victoria.
That is where this series both begins and strangely enough ends.
The first book is titled "The Strange Affair of Spring Heeled Jack" who is an English folklore centered around creatures capable of leaping over buildings and causing various bouts of mischief. However, this particular version of Spring Heeled Jack is in fact a time traveler from the 23rd century named Edward Oxford who went back in time to prevent his ancestor, also named Edward Oxford, from successfully assassinating the Queen thus forever staining his family name.
But, as any history buff would know (or someone with access to Wikipedia for 5 mins), Queen Victoria was never successfully assassinated by Edward Oxford. He historically missed both shots before being taken into custody. So you have to ask yourself, what could possibly have happened to change that? Well, it was a combination of both Edward Oxford in disguise and Edward Oxford in his Spring Heeled Jack themed time travelling suit as well as other events set in motion that caused that event to divert from its original path into totally unknown territory.
And boy, does it get weird.
In a history steampunk story for the ages, Britain goes down a different path filled with fascinating applications for science without the convenience of morality or even basic common sense. In the second installment of the book a leading political faction in Britain called the "Technologists" team up with the "Eugenicists" to create hybrid vehicles for public transport. Namely, enlarging insects to humongous proportions, emptying out their bodies of all their organs, then replacing them with steampunk style mechanics. By the third book they had:
-A centipede bus
-Daddy long leg spiders for transporting goods underneath their bodies which were later retrofitted with gatling guns to be used as tanks during World War 1
-In the future version of the war, they did the same thing to Hornets using them as a substitute for planes.
And that isn't even the half of it. For the German side of the conflict they got the Eugenicists on their side so the Brits renamed their faction the Genetists. Either way, this is what they brought to the table in the war:
-People with expanded mental powers that could control the weather
-Plant based weaponry as well as plant based vehicles such as a walking mesh of vines that have a bunch of thorns used to whip foes into a million pieces. They also were the first to create a sort of Atomic Bomb with their plant pollen that was so small that it got in through the pores of the human skin than ate em from the inside out.
It gets pretty crazy. And that is only the backstory/environments. The actual story itself follows along with notable historical figure Sir Richard Francis Burton and poet Algernon Charles Swinburne. Also, every person in this series is NOT a made up character and are in fact real people put into circumstances they weren't used to and had to adapt.
There is so much to this series that I can't talk about everything lest we get into heavy spoilers, but it is an interesting time travel/alternative history tale. I certainly did not see the ending coming at all.
So yea, if you want to check it out, the first book is mentioned above while the other two, "The Curious Case of the Clockwork Man" and "The Expedition to the Mountains of the Moon", are already available with a fourth book that is in no way related to the trilogy is also available which I will take a crack at as soon as I am able.
