My son has always struggled to stay interested in books but this one is different. He reads it every single night before bed and comes downstairs every morning with a new fact to share with the family. Worth every penny.

I was skeptical at first because my kids never stick with books. Three weeks later and they're still fighting over who gets to read it next. Their teacher has already noticed a difference in how they participate in class.

I bought this as a Christmas gift for my 9 year old and it was hands down the best gift under the tree. He ignored every other toy and sat reading this for hours. Three months later he still picks it up every week. I've already ordered a second copy for my nephew.
