Juniper, a kind snowshoe-hare conductor with a brass lantern, needs an assistant for the overnight run to the North Village. Children seat passengers in rows, stoke the firebox and share cocoa fairly, keep the timetable on a pocket watch across a moonlit frozen lake, set the junctions in a glacier canyon and find lost parcels under the aurora. Everything they solve lights up the village and its giant tree at the end of the line.
