World Engines – Destroyer, by Stephen Baxter
I am very happy to state ‘upfront’ that, except for the ending, I have enjoyed reading this book more than any other I have read, of any genre, for a long time; that might seem like a contradiction, but my enjoyment of the main body of the narrative was not diminished unduly by the short final section, which was something of a disappointment. I can’t reveal any details of the final section, naturally wanting to avoid spoilers, but I felt that, after such a comprehensive narrative, in which Baxter has allowed time for the folds in the story to be revealed & explored, the ending could have been longer and more detailed: it was as if he knew a sequel would have been a better way to wrap the story up, or even develop it some more, but in the end, he couldn’t be bothered, or he ran out of steam, so it was just a question of tying up all the loose ends as cleanly as possible. Enough of that for now, though, because you need to know what the story is about! Ahead of the characters & the plot, what I enjoyed about the story was the elements of alternate universes and time periods, rather than time travel per se, but also the fact that the fantasy was very much rooted in the real world that we know, instead of a fictitious universe full of alien races & technology that is unknown to us and, given our current level of knowledge, impossible.
The story starts hundreds of years into earth’s future, the year 2469, precisely, when earth has suffered the climate catastrophe that is now widely predicted. A man is woken from a cryogenic sleep, and it appears that he is a space shuttle pilot from the early days of the 21st century; so, our own time now, but subtly different in the state of space technology (and the political history that has allowed this to be created). He is conversing with a form of artificial intelligence (AI), and he has been woken earlier than he might otherwise have been, given that he suffered a devastating accident which left him very badly injured, because a message has been received from Phobos, one of the satellites of Mars. The main problem, apart from some significant differences in the sequence of events that led up to the sender’s distress call is that it is impossible, because the sender couldn’t be there in the first place, because she is Emma Stoney, the wife of the pilot, Colonel Reid Malenfant, and her ship was lost when it reached Phobos. In this timeline, Mars was already colonised by 2005, and there was “some kind of puzzle with Phobos”, but it was easier to send a dedicated mission from Earth than to have the Mars base colonists do it from the ground. Unfortunately, the problem with Phobos is inextricably connected with an event known by everybody by the name The Destroyer, which is predicted with some accuracy it would seem, by the AIs, to occur in the year 3397, resulting in the destruction of Earth and very possibly also much of our solar system.
Malenfant is sent back to Earth from the moon, where he had been kept in cold storage, and he is assigned a humanoid AI with medical specialities, to monitor & supervise his recovery, and he befriends a young woman who is also assigned to him as a sort of cultural advisor. The Earth of the twenty-fifth century has a well-established resource based economy (the long-term result of a very surprising innovation by one of the best-known 20th century American politicians: and not who you might think!), as money is no longer necessary, apart from occasional exceptional circumstances; the population doesn’t have to work for a living, because all necessities for a comfortable life are freely available: the fact that the population is much reduced as a result of the foregoing upheavals is a positive contributory factor here. Malenfant is curious as to why the populace seems to accept unquestioningly the impending fate of Earth, albeit in the relatively far distant future, but when he speaks to the Earthbound AI, he discovers that it is distinctly worried (displaying a surprising level of human empathy), so he sets out to find out more about the problem with Phobos, which seems to be the root of the danger. Using by then outdated space technology, but with which he is familiar from his own experience, he manages to get to Phobos, which is where the story becomes distinctly strange……
This is about as much as I can reveal without spoiling the plot, but if you enjoy space fantasy fiction and, especially, if you have read any of Stephen Baxter’s other books, either solo or with Terry Pratchett, I am as sure as I can be that you will enjoy this one. The paperback version I read was published in 2020 by Gollancz, London, ISBN 978-1-473-22319-6. This is a book to really luxuriate in, and revel in the way the plot develops quickly enough to retain your interest, but not so quickly as to leave you gasping for breath. As I said, the ending seemed tantalisingly short, but I don’t think it leaves the way open for a sequel: should that be the case and I am wrong, however, I would be eager to read it!
