Recs if you like Semiosis...

SFF featuring second worlds and storytelling that reflect and engage with hopes, anxieties, and imaginations about human activity and its influence on the environment + environmental justice. Always open to suggestions! (Note that I am using “second world” very loosely here, to mean both traditional second worlds and/or versions of Earth or parts of Earth that are so distant/strange as to be unrecognizable)

Fiction books featuring plants as a major theme. For the purpose of this list, fungi are honorary plants! All fiction genres here (though I am primarily a fantasy reader, so suggestions most welcome!)

a list of sci-fi books containing aliens

Self-contained SFF books that belong to a series, offering a complete story without a multi-book commitment. A perfect way to sample immersive worlds while limiting potential disappointment – yet still leaving more to explore if you liked it.

First Contact with Aliens Sci-Fi Books

Sci-Fi horror novels set off-world (written by fem and non-binary authors)

fiction novels that contain two different species melding together and forging a relationship for the good of at least one of them! because remember, parasitism is a symbiotic relationship as well. mainly science fiction but spans all fiction!

I love mushroom-related horror, and these are all the books I have found that use spores, fungus, or mushrooms as the antithesis of the book's horror.

“Summer” reading list with novels in a variety of genres about a variety of sea creatures.

At Nohara66's request, scfi books "without space and physics!" (Or as close as can be). Some of these do feature spaceships in the background or as a step from point A to B, or set within galactic empires, or once colonised worlds, but involve no physics and don't focus on life/travel in space.
