The Minions have not put this down, and after reading it, I can totally understand why. Bright colours, fun illustrations, and lots of fun facts. This is a house favorite!

Great pictures! Loads of interesting facts! I learned so much, and will be returning to this book for reference! What a fun idea.

They mentioned some things that are theories, or even hypothesis, as if they were verified truth. It's alright to mention it, but I would have rathered they'd at least let us know when something hasn't been proven, instead of claiming it as a matter of fact. It felt like they slipped a bit into propaganda at times?

I love these books so much. Great and creative corresponding illustrations. I appreciated the chapter about Denali's many names across time. And the chapters about what is going wrong with the planet (thanks to humans) and what possible demises of the planet could be. Scary but interesting!

Ihan hyvä tietokirja, tavallinen. Pienikin voi ymmärtää, vaikka asiat on enemmänkin vanhempien asioita. Sini-ihmistietokirjat on parhaita, joten tämäkin on tietokirjojen aatelistoa :D
