I am very appreciative of Adrian Tchaikovsky continually putting out solid standalone science fiction novels. His latest book, The Doors of Eden, is the next in a long chain of satisfying and meaty stories that are nicely contained in a single novel. Tchaikovsky’s latest novel has cemented him in my mind as a reliable author who always has something interesting to say and explore with his novels. As you might have guessed, I enjoyed The Doors of Eden, and I suspect that you will as well.
The Doors of Eden is about parallel Earths. In this story, there exists a multitude of timelines dating back to the dawn of life on Earth, each with its own branching path to evolution. The story explores the question “what if the dominant species of different eras of Earth’s history kept evolving and became the dominant lifeform?” As usual, Tchaikovsky sets these ideas up brilliantly and the exploration of what a society of Trilobites looks like is fascinating. There is this cool “strangeness” paradigm that he uses in building the societies which really tapped directly into my imagination. The closer to the dawn of Earth a species is from, the longer they have been around to advance their technology – and the less they resemble humans. Thus, the older species are god-like spacefarers that humans struggle to communicate with, while the younger species are something like “rats who have cured cancer.” It was a cool way to lay out all of Earth’s history and did a better job of teaching me the differences in the prehistoric eras than any high school course did.
The tension in our story comes from reality collapsing (no biggie, obviously). A group of scientists across the parallel Earths realize that realities are starting to bleed into one another and citizens from different Earths are leaking into non-native parallel worlds and scaring the locals. They also realize that these leaks are heralding the end of all existence entirely, and decide to band together to see if they can maybe stop it.
The narrative in The Doors of Eden is split into two different story types that alternate between chapters. The first storyline is the present, where a ragtag group of characters is trying to keep reality from ending. The second storyline is academic vignettes that dive in, catalog, and explore all the different versions of Earth and how they came to be. The academic vignettes are incredible and sucked me into the book as violently as explosive decompression. The present storyline was also very enjoyable but had a couple of issues that kept me from loving it with the ferocity of the second narrative.
The vignettes have no specific characters and are told from a distant academic point of view. The present story has a myriad of characters that I had mixed feelings about. The first (and greatest) character is Kay Amal Khan – a male to female transgender math god who is leading the ‘keep reality from ending’ effort on the human side. She is funny, fierce, brilliant, and has both a scientific and personal arc that I was heavily invested in. Tchaikovsky managed to give a lot of time exploring the discriminatory garbage that trans people have to put up with while also losing none of his signature sci-fi concepts. She is wonderful and I would die for her.
Up next we actually have an antagonist, sorta. The real antagonist of the story is the heat death of the universe, but Lucas is the right-hand man of another man who isn’t improving things. Lucas is a complicated character who falls into being a bad guy and doesn’t know how to stop. He doesn’t necessarily have a redemption arc, but his story does an amazing job exploring how the tiny choices we make build momentum into who we become, and in some ways how our circumstances–not our inherent nature– determines whether we are good or bad. His story is great; you will have to read the book to understand it better than I can reasonably explain here.
Then we move to the lesbian teenagers in love, Lee and Mal. They are fine. Their story isn’t particularly interesting, and they don’t feel like they mesh well with the urgent narrative – but their budding relationship is still enjoyable and they have relatable personalities. They felt like they were around to catalyze a few “aha” moments for other characters and I wish they had a little more agency in the actual story.
Then we have the MI5 agents, Alison and Julian. Alison is also fine. The two of them mostly seem to exist in the story to foil the rest of the characters and argue that strange events the reader knows are happening actually aren’t happening. However, while Alison eventually becomes more integral to the story and has some agency, Julian’s entire deal is to continuously whine about how he doesn’t really love his wife and secretly wants to bone his coworker (Alison). He refers to it as the “unspoken connection” they have, then talks about it in his head constantly. Not a huge fan of him.
In addition to the characters, the science also has its ups and downs. The parts that cover the evolution of other Earths are detailed, imaginative, and exciting. However, the parts of the book that actually talk about trying to fix reality usually involve some people going off-screen and “doing some math,” then coming back and reporting whether it worked or not. On the one hand, it isn’t a huge detail as the themes and ideas of the book are more closely tied to how the characters process the multiple Earths – not the actual fixing of reality. On the other hand, given how delightfully detailed the other Earth vignettes were, I found it disappointing that Tchaikovsky just handled the crisis-solving off-screen.
Overall, The Doors of Eden is a great book with both heart and science. Tchaikovsky has a real talent and imagination for alternate realities and seems to have a vault of ideas to explore that never runs out. I absolutely loved the glimpses in Earths that could have been, but the characters that were the focus of so much of the story were a bit mixed. Still, I definitely recommend this standalone sci-fi novel as one of the most enjoyable things I have read this year.
Rating: The Doors of Eden – 8.5/10
