Oliver in the Hunter Stone Age is the first volume in the series about Oliver in the Antiquity. The book teaches children about older time periods and cultures in a entertaining way.
Oliver is on a field trip to Lake Flixton with his preschool, when he suddenly falls into the water. Luckily he is saved - by a large bearded man wearing skin clothes. Oliver has mysteriously ended up in the Hunter Stone Age. Now he must learn to handle himself in a camp over 6000 years ago.
The book is written by Andreas Valentin Wadskjær og illustreret af Gonzalo Vento.

Rejsen i Litteraturen: “The beauty of the book is that its knowledge is unfolded through Oliver's 5-year-old eyes and mind, whereby he asks questions about his surroundings, and learns about the Stone Age at a child-friendly level. Among other things, he learns about the Stone Age people's way of living, as well as how they dress and cook. In addition, Oliver learns how to chop flint, produce axes and use nature as a toilet

Æseløre: “Andreas Valentin Wadskjær, som er cand.mag. i forhistorisk arkæologi, benytter sig af det klassiske greb og sender en nutidsdreng tilbage til fortiden. Hans ærinde er at fortælle om livet dengang set gennem Olivers øjne. Det lykkedes ret godt. Historien er lærerig, men også Olivers tidsrejse er spændende. Læseren kan være bekymret for, om han nogensinde kommer hjem igen." Read the entire review here.
