In Ember Market, twelve-year-old Rumi and his friends embark on the Marketplace Money Mission—a day-long contest to turn ten shiny tokens into profit and community impact. As they bake pastries, craft bracelets, and record each expense in a hand-drawn ledger, Rumi negotiates bulk discounts, adapts prices during customer rushes, and plans for emergencies when a mixer breaks. Through savvy budgeting, dynamic pricing, generosity, they learn economies of scale, contingency funds, and the joy of giving back. At dusk, ribbons reward best budgeting, highest profit, and biggest donation. This spirited adventure brings financial literacy to life in a fun, heartwarming tale.
