In the mood for a mind-twisting yet heart warming (at least to me) short story? May I recommend The Egg by Andy Weir? Recommended to me by my 30-year-old kid. She's got great taste. https://www.galactanet.com/oneoff/theegg_mod.html (She also introduced me to Becky Chambers. She's a huge fan. Like I said, great taste.)
