The Psychological genre of books typically explores the inner workings of the human mind and emotions, often delving into complex and sometimes disturbing psychological states.

Psychological books may be suspenseful, thought-provoking, and emotionally intense, offering readers a deep and often unsettling glimpse into the human psyche.

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.
