The Doors of Eden,
Hardback, 608 pages,
Published August 2020
After the recent Children of Time and Children of Ruin, as well as Firewalkers, it is fair to say I was very eagerly anticipating Tchaikovsky’s new stand-alone novel. As with the Children series, this is a huge tome of a book, but don’t let the size daunt you – like Peter F Hamilton’s books, when you start reading them they are so engrossing and so well-paced it doesn’t feel like you are working through a massive page count, you will be quite happily enraptured with both the story and the myriad of ideas it sparks inside your head.
Two young girlfriends, Mal and Lee, take a short holiday of sorts – they love exploring reports of cryptids together, and even write them up for publications like the Fortean Times. Naturally both like the idea of mysterious creatures, unknown to science, but they are also intelligent enough to know that most reports are mistaken identities (it turns out the giant panther was a domestic cat and someone couldn’t judge distance and size in the dark) or out and out fabrications. What happens, though, when it starts to seem like there may be more to a sighting on the lonely moors than they suspected? What happens when a set of three ancient standing stones, known as the six sisters, despite only numbering three, becomes, right in front of their eyes, a circle of six? And when snow blows across the midsummer moors in an instant, with strange beings glimpsed in the storm? What happens when Mal vanishes?
Four years on and Lee, still wondering what happened, if she imagined things, if she went mad, is still missing her friend and lover, when Lee returns, looking different, but definitely her. Where has she been? Why so long before returning to London? Lee’s return is linked to a number of other events though – other strange disappearances, a remarkable breakthrough in computational maths and physics that could bypass all the top-secret encryption used by security services the world over, a manipulative billionaire with connections to both political heavyweights and low-life Neo-Nazi boot boys… And, perhaps something even larger, something which has a bearing on the very nature of existence itself.
Within the first hundred and fifty pages or so Tchaikovsky gives us a story of intrepid cryptid explorers then adds in scientific breakthroughs and elements of a spy thriller. This is more than most novels do in their entire page count! And then there is the fascinating and compelling element of multiple realities. The multiverse is no stranger to SF readers, of course, from Moorcock to the Adventures of Luther Arkwright and many more, and indeed it is a concept taken seriously by many in the scientific community nowadays. Here, in addition to the idea of multiple Earths in parallel realities, Tchaikovsky also deftly indulges in a lot of evolutionary what-ifs.
This isn’t just the old, here is the Earth where the Allies lost WWII, or Rome never fell approach (not that I have anything against those, tales, when done well), here, as with the Children books, he takes the very long-term view, exploring multiple evolutionary approaches on Earth. There are some where dinosaurs never became extinct and evolved into intelligent lifeforms (yes, I know, technically not all dinosaurs died out, some evolved into the bird family, and indeed that idea is also nicely explored), others where the huge sea scorpion type creatures became the dominant life millions of years before even reptiles or dinosaurs, let alone mammals or humans. But in each, while all the various possible lines of evolution play out, each Earth still suffers the same massive traumas, the same mass extinction events caused by ice or fire or meteor. Some vanish into these cataclysms, others adapt only to be lost later in the vastness of geological epochs passing (we are talking millions and billions of years, after all). We even get to ponder that remarkable evolutionary accident that had more than one type of intelligent human life existing at the same time on the same world (our own) and how that played out in other Earths closer to our timeline.
The main arcs of the story have some fascinating excerpts from a book on these parallel evolutions on other Earths, which explores so many possibilities (and yes, it does also allow Adrian to indulge in having some multi-legged creatures in the book, of course!), and I found these as intriguing as the main story. We have an engrossing story, some terrific characters (and also, I should add, a nice bit of diversity there, including gay and trans characters, and that’s just among the humans, which was very welcome), and a gradual layering of all the various strands which take the story off into a different direction than you may at first suspect, upping the stakes for the characters, indeed for all of the various worlds, each time we learn something new, and at points even incorporating the multiverse story into the actual structure of the writing to give multiple perspectives and possibilities.
This is simply superb science fiction, a gripping, high-stakes quest, and some staggering concepts that will leave you thinking about all those many possibilities, all those what-ifs that made our world – and the many other Earths – what they became.
