Perhaps the novel delves into the idea of the unknown. Girls, with their different behaviors, emotions, and ways of thinking compared to boys, can seem like an enigma. This sense of the unknown could be what makes them 'scary' in the context of the novel. It could show how characters in the novel gradually overcome this fear as they get to know girls better.
One possible theme could be friendship. The two girls are sharing these scary stories, which might strengthen their bond as they experience the thrills together.
One possible theme could be discipline within a female - only community or group. For example, in a story set in an all - girls school in the past, spanking might be used as a form of punishment for breaking rules. However, this is a rather old - fashioned and controversial theme.
The theme could be about dreams. All the girls in the novel might be chasing after their individual dreams, and the story could revolve around the obstacles they face and how they overcome them. Or it could be a theme of growing up. As the girls grow, they have to deal with new emotions, new responsibilities, and changing relationships, which can be a central focus of the novel.
Fear of the unknown could be a theme. When looking through a keyhole, you can't see the whole picture, and that might create a sense of unease.
One possible theme could be female liberation. It shows women enjoying a form of entertainment that was traditionally more male - dominated. Another theme might be body acceptance, as the male strippers are comfortable with their bodies and showing them off.
One possible theme could be female friendship. Girls often have strong bonds, and this could be explored in the novel.
Another theme could be the forest at night. The French countryside has beautiful but sometimes eerie forests. In the story, there could be strange creatures like werewolves or witches that lurk in the shadows of the trees, waiting to catch the unwary.
Another theme might be self - discovery. The close - quarters situation can make a person, especially a male character, re - evaluate his views on girls, relationships and his own identity. It could be a journey of learning about empathy and understanding. Also, there could be a theme of survival. They need to find food, water or a way out, and in the process, they might learn about human nature and the will to live.
One possible theme could be friendship. Girls in a town often form close friendships, and the story might explore the bonds they share, like how they support each other through tough times or celebrate joys together.
One possible theme could be the supernatural. This includes ghosts, vampires, and werewolves. Another theme might be mystery, where the stories keep you guessing until the end. For example, a mystery about a missing person in a spooky forest.
