Mac Harkdonk: Secrets of the Earth Beneath the Earth

Wow! Whoa! The first four books of the series are a story of the mysteries and beauty and human challenges of nature around us. First of all, there's a story of a dinosaur that lived on a very long and distant planet, the real natural magician, the amazing animals and plants. And there's a story of people who have invented the dream of a planet in mysterious soil and space travel and had their first footprint on the moon. It's going to be really interesting, right? You're going to read these stories in a kind of unhesitating way, and you're gonna cry out in my mind,. Wow! Whoa!
