Book excerpt: ‘Jill was an open book’ he’d said of his wife. She does as she’s told without hesitation, endures the pain he dishes out, and calls him “Daddy” when she’s scared. She’s his, right? But then there’s Benny. To him ‘Benny was just an amusement park ride, a crude piece of entertainment machinery: easily started, stopped, calibrated, controlled.’ Only problem, Benny meant something different to Jill.
