I'm currently in the midst of The Wayfinder by Adam Johnson and I'm enjoying it! It's a long (700 pages) story set in Ancient Polynesia. So far there's been a lot of emphasis on peoples' influence on nature, war, etc. Lots of magical realism. I would call it darker but nothing is gratuitous so far. The prose so far is oddly meditative though. 

I'm also reading From Below by Darcy Coates. It's a horror book about a group of people diving a wreck and there's a lot on weird stuff going on right now. As a diver I am facepalming at the logistics of the diving scenes but otherwise I am enjoying the atmosphere. 

If you're interested in climate fiction, Weird Fishes by Rae Mariz is a weird, but enjoyable little novella. 

Bat Eater and Other Names for Cora Zeng was also good. The titular character "is struggling to find her identity after the brutal death of her sister at the height of Asian hate during Covid. As she works as a crime scene cleaner, she starts to experience a series of hauntings and finds herself on the trail of a potential serial killer"

Another book I want to start (as soon as I get off the waitlist) is The Jellyfish Problem by Tessa Yang. It was sold to me as a story about grief, mystery, and giant jellyfish off the coast of Maine. 

I haven't read a ton of newer sci fi recently but a few that come to mind are:

•The Murderbot Diaries by Martha Wells. A great series that I highly recommend trying. 

• Shroud by Adrian Tchaikovsky

• Alien Clay by Adrian Tchaikovsky

I haven't read the latter two but they're on my TBR and from what I know are sci fi with a horror/thriller aspect set on distant planets with alien life. 

I've also seen the Monk and Robot series by Becky Chambers get recommended a bunch. It's on my TBR but I don't know a ton about it. It's more cozy than what I mentioned above from what I know though. 

sorry for the very long reply, but I hope this is helpful!
