Hypothetically this his Hugo Awards homework, but I'm not actually entirely sure that it's SF/F/H, or if the point of view character just spent a majority of the book lost in a metaphorical nightmarescape. Certainly, it's a slight alternate reality, as everyone's mother spends their time washing the bones of their ancestors in the household bathtub, something that was meant to be some sort of spring cleaning, but has become a daily obsession in the main character's household (meaning no one can have a bath now, a point of some contention). Meanwhile, the main character has both nightmares and waking dreams about being trapped in an infinite hotel, which would seem quite nice except for its astonishingly foreboding and creepy atmosphere, and the fact that it seems to be a shared reality that spills into other people's dreams and indeed the real world.

Basically all of this is a metaphor for the Korean War, and how it never ended, and each generation has to come to terms with that. Our heroine spends the entire book milling around, feeling stuck, having nightmares, failing to cope, getting in arguments with her immediate family, not getting to have a bath, and being overwhelmed by the recent death of her father. Nothing actually ever happens? That I could tell? She just feels existential dread for three hundred pages?

Very slow read with great vibes, but I might have connected more with it if I was Korean. Unclear.
