I'm not sure I know of any that are similar to the 3 Body Problem that don't involve space. But if you're just asking about SF in general... Spin, which I mentioned above, takes place entirely on Earth. But it's definitely at least somewhat "space-related" in terms of its plot. Caves of Steel by Asimov is a certified classic who-dunnit in a far-future underground New York City. If you're interested in golden age scifi at all, this is a great one to check out. Anathem by Neal Stephenson is one of my favorite books of all time. It has a tiny bit of space in it, but the whole book pretty much takes place on a single planet. Permutation City by Greg Egan is all about computer-simulated consciousness. Thought-provoking but also a bit horrifying. I also love Fine Structure by qntm (author of Lena[0]). Though it's a bit rough around the edges, I find that every time I pick it up to re-read it, I can't put it down until I'm done. Those are just some ones I personally like. There's more I could list, but SF is a very wide genre and I have my biases — you should check out /r/printSF for some more broad recommendations maybe. 0: https://qntm.org/lena https://qntm.org/lena
