Fiction is the term for any invented literary narrative or, more broadly, anything made up. In literature, it refers to novels, short stories, and other works of art that do not purport to tell true stories. Science fiction, mystery stories, and romances are among the popular subsets, or genres, of fiction.
Several recurring tropes and sub-genres exist within crime fiction, including detective stories, political thrillers, and heist tales.
The genre is flexible enough to bleed into other fiction genres, such as science fiction and classical horror.
In some cases, romantic fiction may incorporate other fiction genres, such as mystery, fantasy, or science fiction.
Romantic novels may also contain erotic writing, though many sharply limit description of intimate contact between characters.
A thriller is a book which is designed to keep the reader or viewer on edge with suspenseful and sensational action. This genre is incredibly large, and thrillers often overlap with pieces of work produced in other genres; mysteries, for example, are often thrillers.
Several characteristics help to define a thriller. Thrillers typically involve sudden plot twists and lots of red herrings, for example, keeping people unsure about what is going to happen. This suspense can get almost unbearable. Thrillers also have a lot of action, which is often chaotic, and they typically feature resourceful heroes and exotic settings.
