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."

"My daughter has never once picked up a book without being forced. I left this on the coffee table on a Friday. By Sunday she had read half of it and was explaining to her grandfather why the moon doesn't fall out of the sky. He's a retired engineer. He was impressed. I was speechless. This book is something else entirely."

"Bought this for my grandson's birthday not knowing what to expect. He opened it, looked at the cover for about thirty seconds, and said 'is this actually mine?' He read it at his own party. His mum called me two months later to say he'd read it three times and was asking if there was a second one. Best gift I've given in years."

I bought one book and they sent me three. Guess I'm giving them as gifts! Super interesting book that my son loves to thumb through when he's bored or before bed. Illustrations and information are great.

I really liked the content! Great book! I loved the little bookmark detail

J
Jenny

Content seems interesting however quality is well below par and not what is advertised. We have a word missing on one page and most other pages looks like the printer ran out of ink or the font is different from page to page. It also arrived damaged which would be fine if the rest was high quality. Emailed first and response was we will look into it but never heard anything back even after a follow up email. Very dissapointed as was a very expensive book considering the quality.

My daughters (7 and 9) absolutely LOVE this book. They each got a copy and spent the first night reading for hours together. They subsequently shared all the amazing information they learned with us and their teachers the next day.

I was pleased that the book arrived earlier than expected. I have not opened it up, and it’s a Christmas present for my niece and nephew. But I’m sure they’ll love it and get lots of use out of it!

It's written in a way that most concepts are pretty easy for children to understand. I have learned a thing or two myself!
