One minute, Noah’s digging through his grandpa’s attic. The next? He’s zipping through history with Midas—a golden coin who’s part time-travel guide, part ancient money wizard, and 100% not your average piggy bank. From fishy trades in the Stone Age to seashell currency, emperor’s IOUs, gold coins, and glitchy Bitcoin bots—Noah discovers that money isn’t just stuff you spend on snacks... it’s one of the trickiest and most powerful inventions in human history. Packed with adventure, laughs, and real financial wisdom, What is Money? kicks off the World of Money series: a kid-friendly dive into the world of finance and how to make, save, spend, invest, and share money —without stuffy jargons. Iris Wang is a global investor, storyteller, and mom on a mission to help kids unlock the power of money with curiosity and confidence. After years of navigating financial markets and dinner table debates with her two brilliantly opinioned sons, she created the World of Money series to bring financial wisdom to life through laughter, wonder, and time travel. She wrote this book with love, passion and with creative sparks from Nova—her AI co-pilot who speaks fluent kid, code, and coin. “This book started as a bedtime story... and turned into a financial adventure I wish I had at their age. Helping kids make sense of money is the most powerful investment I’ve ever made.” — Iris Wang, Author Iris Wang is a global investor, storyteller, and mom on a mission to help kids unlock the power of money with curiosity and confidence.
