Curate, connect, and discover
a story (told through a book, visual novel, graphic novel, or smth else) where the narration (in third person, can be 3p omniscient or following a pov chara) starts out seemingly reliable before going progressively more off the rails, especially in the third/final act. on first reading it isn't apparent that this will happen, but on future readings little hints and symbolism along the way leave little clues to it happening
