Great video! Legends & Lattes is such a fun book (it gave me very similarly pleasant vibes to The House in the Cerulean Sea)! Edited to add something that is hopefully at least somewhat on topic: "The Left Hand of Darkness" is one of Ursula K. Le Guin's anthropological science fiction books that's on my TBR, and is about "an alien world whose inhabitants spend most of their time without a gender." The fact that Le Guin was exploring topics like this in the 1960s is pretty cool.
Yes I definitely see the similarities to House in the Cerulean Sea! I definitely need to pick up Left Hand of Darkness that sounds like a great premise-honestly, I’ve never read anything by Le Guin and I should remedy that.
