This Is How You Lose the Time War by Amal El-Mohtar & Max Gladstone
When I was younger I remember reading a short description of Fritz Leiber’s The Big Time when it was reissued for the Science Fiction Book Club and being fascinated by the idea of a time war. I still haven’t gotten around to reading Leiber’s exploration of that idea, so I can’t say for certain how closely Amal el-Mohtar and Max Gladstone were informed by it in their new co-authored novel, This is How You Lose the Time War.
The general idea of a time war though is fairly straightforward and has been a recurring science fiction trope since Leiber’s work. However, the execution of one (and writing a narrative that follows the agents waging one) is anything but. The theme works like this: assuming two sides have different desired and opposing outcomes for the future and that any future is the outcome of a millions accumulated events, waging a time war means sending agents or soldiers into the past to change the outcome of these events so history flows one way or another. This could be changing the outcome of a historic battle, causing the assassination of a specific individual, or even things more subtle like influencing a particular political leader as she develops her ideas.
Now overlay all this with a love story. That is what El-Mohtar and Gladstone are about in this very gorgeous book. The two sides in their eponymous time war are diametrically opposed: one pushing history toward a technological utopia with forces overseen by the cool, calculating Commandant and the other toward a future in which everything — even the stars themselves — has become part of a vast organic hive-mind called Garden. The Commandant’s best agent is Red, and her opposite for Garden is known as Blue. It’s difficult to classify either agent, who are the dual protagonists of the story, as human. Both have been synthetically created by their respective side with immense power, in addition to time travel (the mechanics of which are kept vague throughout). Both identify as female, and both fall very much in love.
The structure of the book is crafted around a series of letters between Red and Blue as they strike up a dangerous, flirtatious rivalry that quickly grows into much more. Each short chapter (which read almost like vignettes or carefully crafted prose poems) follows either Blue or Red in a different period from Earth’s past to the far future as the one’s missions are foiled or obstructed by the other. Each chapter ends with one finding a letter left by the other. The imagery throughout, especially in the letters, is striking, bringing each new landscape to life, and consistent enough it’s hard to tell where one author’s writing ends and the other’s begins.
