Unfortunately, Indonesian knowledge books still can't compete with English ones. Maybe because the demand for good books are still low. That being said, English book like this is still the best option to grow young minds. This is a great gift for my nephew.

The language is not hard to be grasped (this is another positive things with English book, they write in the level that can be understood by the market of the book). The pictures are great and far from boring. I also like how they present the knowledge, it's flowing. So, it won't give as much pressure as school-level learning give.

A quite surprising fun facts. lots of cool stuff to be known.
