I was inspired by the_escapist's challenge on the Storygraph "Explore Fantasy Sub-Genres". Since I loved that fantasy challenge and the kind of books it's making me read, I'm creating one for sci-fi. It is meant to encourage people to read more sci-fi books and sometimes books different to what they usually read.

It would be best if participants use a different book for each category (it makes it more challenging) but feel free to do what fit your reading style best. Different books in a series can count for multiple prompts.

There's no time limit for this challenge.
