Everybody points to epic fantasy because of 'Stormlight Archive' and 'Mistborn', and that's definitely his core lane. But I've always thought the man writes sci-fi too, just dressed in fantasy robes. Take 'The Alloy of Law' and the later Wax and Wayne books—sure, it's on the same planet, but the tech level, the detective noir vibe, the whole frontier-with-trains-and-gunfights thing? That's a genre blend that leans hard into something else. Calling him just an epic fantasy author misses how he treats every story like a magic system puzzle box, regardless of the setting's trappings.
Even 'Skyward' is straight-up young adult sci-fi with dogfights and alien planets. The genre feels almost secondary to the mechanics of his plotting and worldbuilding. He seems to specialize in intricate, rule-based universes where the 'what if' premise is king—and that can manifest as fantasy, sci-fi, or a mash-up. The throughline isn't dragons or lasers; it's rigorously exploring a premise's implications.
