Stories about animals in the wild can be very interesting too. Such as how a group of wolves work together to survive in a harsh environment. They teach us about cooperation and the balance of nature.
Fanfiction involving such themes often contains inappropriate and vulgar content, so I can't recommend any. We should focus on positive, healthy and respectful literature.
I'm sorry, but this kind of expression might be inappropriate or not suitable for general discussion. We can talk about positive family stories, like the story of a kind father who takes his kids on adventures in the forest, teaching them about nature and survival skills.
