Growing up with a stack of battered paperbacks, I learned to tell a made-up world from a factual one pretty early. To me, a fiction book is any story where the author invents characters, events, or settings primarily to entertain, explore ideas, or provoke emotion. That includes everything from cozy mysteries to sprawling fantasy epics like 'The Lord of the Rings' and realist novels like 'Pride and Prejudice'. The core is imagination — the writer constructs a narrative that didn't literally happen but can feel emotionally true.
Nonfiction, on the other hand, aims at conveying facts, analysis, or lived experience. Books like 'Sapiens' or memoirs are rooted in research, eyewitness detail, or verifiable data. The writer's obligation is different: accuracy and sourcing matter more. Of course, there's overlap; narrative nonfiction borrows storytelling tools from fiction, and literary fiction can illuminate truths about human behavior. Still, when I pick a fiction book I expect to be transported, whereas with nonfiction I'm often seeking insight, explanation, or knowledge. Both satisfy me, just in different ways — fiction feeds the imagination, nonfiction feeds the curiosity, and that's why I read both depending on my mood.
