About This Book
Reach for this book when your child expresses frustration with math formulas or views geometry as a dry, abstract chore. It is an ideal bridge for the creative thinker who loves a good story but feels disconnected from the logic of numbers. By framing a mathematical constant as a life-saving riddle, it transforms a classroom concept into a heroic tool. The story follows young Radius, who must save his father from a dragon-transforming potion by solving the mystery of the circle. Beyond the math, the book explores themes of filial devotion, persistence, and the courage to think through a problem under pressure. It is perfect for children aged 7 to 12, offering a playful way to demystify pi while reinforcing that intelligence and empathy are just as important as physical strength in any quest.
