Zero Local: next stop: kindness

". . . in a near-wordless tale . . . [t]rain riders are used to stressful delays on the Zero Local line. But when a new passenger shows gratitude to the driver on their daily commute, tensions begin to ease. Eventually the artistic traveler stops riding the Zero Local line, and discord begins to creep back into the train car. Will the regular passengers find a way to restore the sense of camaraderie they once felt?"--Amazon.
