The low thrum of the engine, the sun’s warmth beating down on the car’s roof, it was all conspiring against Marcus. He found himself struggling to keep his eyes focused on the winding road. He rubbed them with the heel of his palm. His son, Ethan, however, was wide awake, his face pressed against the window, excitedly pointing at the various cars they passed. Ethan's passion for cars, born from Marcus's own long-held interest in automobiles, was a constant source of amusement. The child knew more about horsepower and torque than Marcus felt he knew. Marcus fought to maintain alertness. He knew Ethan would be disappointed if he had to cut the car show short.
