From Heavy Medal:
Put all of your usual critical smarts to work. Look at characterization, plot construction, pacing, dialogue, voice, etc. But also let the book teach you how to read it. Instead of scoffing at the impossibility when Bingo and J’miah start to talk, ask yourself, “Is this what an East Texas bayou raccoon would say, if an East Texas bayou raccoon could talk?”
