I wish my son had a teacher like your sister was. My son used to be an avid reader, but is drowning in his English classes because they are forcing him to read the literary equivalent of boiled kale. He will happily read fantasy or sci-fi (current favorites: Murderbot and Naomi Novik's Scholomance series), but doesn't engage with Great Literature (TM). He tests pretty well in standardized tests, because he doesn't have the same hang-ups about short passages.
