Recs if you like Cage of Souls...

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)

Books that take place on Earth in the far future.

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.
