The new railway's first stop west is a village full of things the valley has never seen, and prices, which the valley has never seen either. When the first Market Day crashes harder than a shy minecart, Miles and Beno have to work out what an emerald is actually for. A story about markets, money, and the difference between counting and caring, with a fox who takes one thing a day, a trader who counts everything, and two very patient haulers whose little book of who needs what turns out to hold the answer.
