What Parents Are Saying
⭐⭐⭐⭐⭐
"My 9-year-old asked me 'Mom, why do we have two eyes instead of one?' I didn't know the answer. He went straight to this book, found it, and spent 45 minutes reading about vision, brains and evolution. He came back and explained it to me. I almost cried. His teacher called two weeks later to say he was the most engaged student in class."

"I was skeptical. My son doesn't read. He's a screen kid. I put this on the coffee table and didn't say a word. Day 3, I found him on the floor reading about black holes at 9pm when I thought he was asleep. He's read it cover to cover twice. That is not a normal thing for him. Buy it — it competes with screens and wins."

"Bought 3 copies — one for each of my kids and one for my nephew's birthday. The dinner table conversations we've had because of this book are priceless. My 7-year-old explained tectonic plates to my mother-in-law. She was completely speechless. This book changes how kids think, not just what they know."
