Having watched Netflix's The Expanse I downloaded Leviathan Wakes, the first of the James S. Corey novels it was based on. Pleasing: he got the conventional physics right and made the unconventional halfway convincing. I nearly baled out when I watched the first Expanse episode, snorting at people clumping around in Ceres' 0.029 g as if they were on Earth, and of course at spaceships making a noise. The book is much better: Ceres was spun up to yield 0.3 g just inside the surface and the rockets don't even hiss. I'm a wee bit sceptical, though, that spaceship hulls would all be ferrous enough for mag boots to work.
