Yes- speculative fiction. Sorry, I'm really new at this and it was the first term that came to mind. I've never really fancied fantasy tbh. I thought it was all elves and fairies. I've seen fantasy films and I just don't engage with them. I'm very happy to be proved wrong. I guess I'm thinking speculative because I love a 'what if'. A philosophical idea explored. Like in Matt Haig's 'The Midnight Library' has, on your death, a library of books, each book containing a possible version of your life. I love that sort of idea.
It's been a long time since fantasy was "all elves and fairies"...
Off the top of my head...
Jade City, Fonda Lee. The Godfather meets martial arts in a modernish world where special jade grants addictive power.
Promise of Blood, Brian McClellan. French Revolution-inspired epic with magic.
Wayward Children series, Seanan McGuire. Deconstruction of portal fantasies.
At work, will add more later...
And back after work, to throw a few more random recs on the pile:
Kings of the Wyld and Bloody Rose (the Band series), Nicholas Eames. A mashup of fantasy adventure tropes with rock band culture in a world of monster-hunting "bands" of adventurers. (Might work better if you're familiar with D&D/classic sword and sorcery tropes, and also some passing familiarity with popular music groups, as there are a lot of winks and nods and Easter eggs - nothing to derail the plot if you don't get them, but fun if you do. And they're great books, by turns hilarious and heart-wrenching, showing that even familiar tropes can read fresh and interesting in the right hands.)
Light From Uncommon Stars, Ryka Aoki. This one's very hard to classify, as it has elements of SF and F. Classical music, deals with the Devil, Asian diaspora, culture clashes, trans issues, fugitive aliens hiding out in a popular L.A. donut shop, and more. (This one took me about halfway through to really click, but builds to a powerful and memorable climax and is one of the most unique tales I've read in ages, if you want to push your ideas of what speculative fiction can do.)
Nnedi Okorafor. Her Akata Witch series has been described as "African Harry Potter", but only in the broadest sense is there resemblance. African magic is not nearly so bubble-wrapped as life at Hogwarts... Her Binti trilogy of novellas, set in a distant future of almost-casual planet hopping and tech yet where tribal traditions and roots still run deep, is a refreshingly non-White perspective on SF, as is her novel Lagoon, about first contact that happens off the coast of Nigeria.
The Dandelion Dynasty series, Ken Liu. Epic "silkpunk" fantasy in an Asian-flavored fantasy world, inspired by the fall of the first Chinese emperor and the scramble for power that ensued. The magic tends to be low-key, but there are meddling gods and fantastic creatures and more.
P. Djeli Clark. I have not been disappointed yet. The Dead Djinn series is alt-historical 1910'sish Cairo in a world where magic and magical beings - such as djinn and beings that call themselves angels and more - have returned. Ring Shout
is a horror/fantasy novella in a 1920's Deep South where demons hide in plain sight under KKK hoods.
The Temeraire series, Naomi Novik. No magic, but an alt-history where sentient dragons exist alongside humans. It starts as "Napoleonic Wars with dragons as living airships", and then the second book onward kicks that door wide open to explore an entire world re-imagined with dragons.
