What Are Popular Book Genres?
The world of literature abounds with different genres. Broadly speaking, the fiction world is divided into two segments: literary fiction and genre fiction.
Literary fiction typically describes the kinds of books that are assigned in high school and college English classes, that are character driven and describe some aspect of the human condition. Pulitzer Prize and National Book Award winners tend to come from the literary fiction genre.
Genre fiction has a more mainstream, populist appeal. It traditionally comprises genres such as romance, mystery, thriller, horror, fantasy, and children’s books.
Romance
Romance often tops sales charts, generating billions of dollars in annual revenue. Romance remains consistently dominant thanks to its broad appeal, emotional intensity, and loyal fan base. Popular romance sub-genres include fantasy romance (romantasy), paranormal romance and historical romance. This genre typically includes themes of passion, intimacy, and emotional connection between characters, and often explores the complexities of human relationships.
Mystery
This genre of books draws a large readership, especially if they’re part of a larger series. Mystery novels start with an exciting hook, keep readers interested with suspenseful pacing, and end with a satisfying conclusion that answers all of the reader’s outstanding questions. Popular mystery subgenres include cozy mysteries, true crime novels, whodunnits, scientific mysteries, hard-boiled detective stories, and police procedurals.
Fantasy and science fiction
These books often take place in a time period different from our own. They often feature magical creatures, from worldly wizards to murderous zombies. Many sci-fi stories take place in a dystopian past or future. Science fiction books can have a historical setting, but most are set in the future and deal with the ramifications of technological and scientific advancement. Fantasy subgenres include urban fantasy, steampunk, high fantasy, epic fantasy, dark fantasy, and sword and sorcery. Meanwhile, certain fiction genres like magical realism blend the pulpy appeal of fantasy with the challenging techniques found in literary fiction. Gabriel Garcia Marquez’s One Hundred Years of Solitude is a good example of this crossover.
Thrillers and horror
Closely related to mysteries and sometimes fantasy, thrillers and horror ratchet up the suspense and shock of popular genre fiction. Authors like David Baldacci and Dan Brown dominate the bestseller list with their thriller titles, while Stephen King reigns as the master of contemporary horror.
Inspirational, self-help, and religious books
These nonfiction book genres reach massive audiences worldwide. Many self-help books concern business success and wealth acquisition. Most titles in the religious category are self-help books that incorporate religious doctrine. They offer suggestions for tackling real-life problems, often from a spiritual perspective.
Biography, autobiography, and memoir
These nonfiction books tell the stories of a person’s life. In the case of autobiography and memoir, the subject is the author of the book. Biographies are written by someone other than the subject themselves. These books are factual information that is traditionally buttressed by multiple sources. This makes biographies different from historical fiction, which is set during well-researched historical time periods but contains original plotlines that aren’t based on real life.
