Postmodernism is a literary movement that emerged in the mid-20th century, characterized by a rejection of traditional narrative structures and a focus on self-reflexivity and intertextuality. Postmodern literature often features fragmented narratives, unreliable narrators, and a blurring of the lines between reality and fiction. It is a genre that challenges the notion of a single, objective truth and instead embraces the idea of multiple perspectives and interpretations. Postmodern literature is often seen as a response to the modernist movement that preceded it, and it continues to be a popular and influential category for contemporary writers.

Existentialist literature is a genre that explores the meaning and purpose of human existence, often through the lens of individual experience and subjective perception. These books often delve into themes of freedom, choice, and responsibility, and may challenge traditional notions of morality and societal norms. Existentialist literature can be introspective and philosophical, and may offer readers a unique perspective on the human condition and the search for meaning in a complex and often chaotic world.
