Seen Reading does something like that, Julie Wilson sees someone reading a book, then tries to guess where they are in the book, quotes the paragraph and gives her impression of the person. Simple yet effective:

She fans the book in one hand, the other reaching into her pocket. She retrieves a tissue and dabs her nose, mouth open, shallow breaths, no scent, no taste. She sniffs and adjusts her weight, assuming the stance of a teenaged girl, face falling soft, skin creased into crepe paper folds.
