This is open to indie too--there's a lot more great indie work out there than people talk about.

I think for me, I've really loved Gideon the Ninth. It's such a FUN book, and I think it's the first science fiction book I've encountered that's also fantasy but also set in "our future".

(Star Wars doesn't count. It's in a galaxy far, far away after all.)

The two sequels are great too. The most recent one, Nona the Ninth, kinda put to rest my fears that the author couldn't write a gentler, kinder viewpoint or world. (The first two books are kinda grimdark in some ways. Like--everything's shit then we all die, then our corpses get raised from the dead and used in necromancer fights. Nona shows us a more hopeful world.)
