This study analyses Michelle Paver’s youth book series Chronicles of Ancient Darkness from an intersectional power perspective. Gender and age are the main elements, and with these two power structures comes another layer of the analysis, namely, the postfeminist idea that it is impossible to categorise people as they are too diverse and ambivalent. Several characters, both youths and adults, are examined to see whether gender stereotypes are followed and if they determine what position of power the characters end up with. The study also explores whether the gender structures vary in groups where adults are present versus in groups where they are not. This adds another perspective, which is the element of age and therefore the problem of aetonormativity. The adults are the norm and they are in charge of the youths. However, when the youths meet with the adults, the two power structures, age and gender, clash in the question of whether a young man gets the upper hand over an older woman, or vice versa. In the end, the analysis concludes that even though the book series follows stereotypical gender structures in several ways, it also presents a query as to whether both gender and age categorisations are accessible and valid. Most main characters question their sufficiency and oppression on several levels, both in insecurities and in open discussion, and this result ends up harmonising with a postfeminist thought pattern. For all to be free from the hardships of not being adequate, or not receiving fair treatment from others based on gender or age, these structures must be questioned and perhaps even challenged.
