Speculative fiction is an umbrella genre encompassing narrative fiction with supernatural or futuristic elements. This includes genres such as science fiction, fantasy, horror, supernatural fiction, superhero fiction, utopian and dystopian fiction, apocalyptic and post-apocalyptic fiction, and alternate history. The unifying factor of speculative fiction is its departure from the narrative constraints of reality, exploring imaginative and often profound questions that challenge our understanding of the world and our place within it. These stories often delve into themes like the human condition, social commentary, and the exploration of philosophical and ethical dilemmas through the lens of the fantastical or the yet-to-be-possible. By pushing the boundaries of the known, speculative fiction invites readers to consider the myriad possibilities of existence and the potential consequences of our actions in worlds that are, at once, vastly different from and eerily similar to our own.

Folklore is a category of books that encompasses traditional stories, beliefs, and customs of a particular culture or community. These stories are often passed down through generations and are deeply rooted in the history and traditions of the people. Folklore books may include myths, legends, fables, fairy tales, and other forms of storytelling that reflect the values, beliefs, and experiences of a particular group of people. They offer a glimpse into the cultural heritage of a community and provide insight into their way of life, beliefs, and customs.

The "Childhood and youth" category of books encompasses stories that revolve around the experiences, challenges, and growth of young protagonists. These books often explore themes such as identity, friendship, family, and coming of age. They can range from lighthearted and humorous to poignant and emotional, and are typically geared towards readers in their early to mid-teens. Whether set in the present day or in historical or fantastical worlds, these books offer readers a glimpse into the complex and often tumultuous world of adolescence.
