Pricey but colorful encyclopedia

Very interesting book but not 100,000 questions. It's kind of like a cute encyclopedia. But an expensive one.

Good quality. Great learning about different things.

This is a fun book. I have it to a granddaughter for summer reading and learning about different things. She loves to learn and is having fun each day.

Much smaller than expected and soft cover

This is not a hard bound book as advertised but a soft cover and much smaller than anticipated. Great book and easy to read to your kids. Fun to read with good questions. Not 100,000 of course

Great bedtime book!

My 7 year old grandson LOVES this book! On a recent visit, he read to me from this book every night. With giggles, his sisters urged him to read the one about “farts”. He keeps it by his pillow, and reads a few pages every night before ‘lights out’. I like the way it explains things without going into great detail. I believe you are never too old to learn something new, and this book proved that! I enjoyed it as much as the kids did.
