I’m in class and there’s one of those dudes-you’ve seen them before-who loves the sound of his own voice. Doesn’t care about getting the point across, loves to be devil’s advocate for no reason other than to feel smart. Out of reflex, I toss my eReader his way, open to Echo. It’s brimming with cyborg ninjas, quantum tech, and zen themes. An armored hand magically shoots out of it and backhands the dude across the face. He shuts the hell up. All hail the cyber-ninja backhand.
