Reading like a writer requires you to figure out what in a piece of fiction moves you and what turns you off. I'm calling that self-awareness your narrative detective—its job is to solve the mystery of the narrative, looking at the ways it is and isn't succeeding—and I'm going to encourage you to feed it PIE every time you read anything: a menu, a short story, the interpretive plaque next to the world's biggest redwood tree, a book.
