A chunk of ash-blonde hair, not yet white like the rest, is matted to Willa’s perspiring forehead. Her body is pasted to the damp sheet that’s pulled off the bottom corners of the sofa-sleeper, eliminating the soft barrier between her bare calves and the rough mattress—she must have been thrashing in her sleep again. She does that when she travels. Her husband, Riley, is standing over her. “There’s a diner down the road. I’m going for fresh coffee,” he says, banging his elbow as he turns in the narrow walkway of the motorhome. “Don’t feed the goat,” he yells, slamming the door behind him. It sticks.
