I'm on book 4 of The Expanse series. 'Hollywood blockbuster sci-fi', set a few hundred years from now, with Mars colonised (but in the process of being terraformed) and other planets' moons providing way stations for air, water and food production. I like that it's from several people's point of view (one per chapter, so it'll make a great shared recording in 150 years or whatever

It's also been turned into a TV show, but I've not seen that yet.
