Disclaimer: I received this book as an ARC from Saga Press, but the review below is all me!
In Yoon Ha Lee’s Code and Codex, we are asked to set aside our everyday understanding of language to imagine a universe where knowing the wrong word renders you into a puppet to a linguo-fascist regime.
Lingua rubra—or “red tongue,” if you are interested in etymology—is the official and only sanctioned language of the Censorate, serving simultaneously as its foundational doctrine and its deadliest weapon.
Valentina dea Regina, adopted sworn-sister to the Peacock, Aurelia Flavinia dea Regina, is tasked with retrieving a forbidden text from a small library hidden in a distant region of space. Normally, Valentina’s duty as the Swan is to eradicate these linguistic “contagions”— i.e. any literature that diverges from the lingua rubra. Differing languages, cultures, histories, or even maps are strictly verboten.
Yet, after being tasked with recovering one such illicit volume by Aurelia, Valentina and her biomechanical serva discover that the book has a sibling of its own. This one is a book of poetry—and despite her duties, her indoctrination, and her loyalty to Aurelia, she decides to secretly keep it.
When Valentina returns to the Urtext Fortress with contraband that would normally constitute treason, Aurelia proudly reveals her scheme: she intends to trick the famous, deadly Basilisk—whose gaze kills with a single glance—into surrendering his power to her with the secrets hidden in the book.
To be completely honest, this book pissed me off. The terminology is jarring, dense, and borderline counterintuitive; I had to drop it, restart, and recalibrate about three times before finally finding my footing. The steep barrier of verbosity forces the reader to endure the same disorienting assimilation demanded of the Censorate’s subjects. Once you survive that initial learning curve, however, the narrative strips down to a razor-sharp core: an arrogant space monarch desperate to cling to absolute power; intricate adoption politics; incestuous devotion; mind-eating slime horrors; and kinetic action that reads like high-octane Warhammer 40K space opera mixed with the wonderfully incomprehensible tenderness of Metal Gear Solid.
Needless to say, I wrestled with how to review it.
Do I give it a low rating because I felt alienated by a world that often lacked tactile grounding, and familiar sensory description?
Do I rate it highly because it makes its case that linguistic assimilation is cultural annihilation?
Do I split the difference, praising the inventive language systems and anti-novel aesthetic while also critiquing it for incomplete relationships or character powers that occasionally run on pure dream logic?
In the end, I have attempted to judge the novel against what it actually set out to do: marry hard sci-fi’s strict experimental systems with soft sci-fi’s human complexity and sociopolitical terror.
Does it stick the landing? Yes—even if it wobbles on the dismount and leaves a few scuffs on the floor.
A 3.75/5 is where I felt the most comfortable with this review (or a rounded 8/10 for Edelweiss). How annoying to bring up fractions at a time like this, right? That’s just the effect this book had on me.
Ultimately, I believe whether someone enjoys Code and Codex comes down to three reader thresholds:
- Mythopoesis vs. Technical Mechanics: Do you need intuitive, character-first world building or do you thrive on learning unfamiliar systems?
- Tolerance for Linguistic Density: What is your appetite for steep learning curves and unapologetically stylized diction?
- Patience with Narrative Grounding: Can you invest in high-concept ideological warfare when traditional sensory anchors and antagonist depth take a back seat to the theme?
It is not an easy read, and it is far from a seamless one. You have to earn your enjoyment of this book in blood and terminology— just like the heroine it follows.
Despite everything, I ended up liking this novel almost against my will. Yoon Ha Lee’s writing has heart enough to make me forget, at least for a little while, how much I want to take away his dictionary forever.
If you like Stellaris, Warhammer: 40k, or Metal Gear Solid, you should give this book a try. It sits at the helm of space operas and demands your complete attention. Alternatively, if you’ve read William Gibson’s Neuromancer, Haruki Murakami’s The Wind-Up Bird Chronicles, or even Neon Genesis: Evangelion by Hideaki Anno, you might be more prepared for this novel than most.
Cheers!
