It is the realm of fairies, of heroes, of dragons, unicorns, and sorcerers. Fantasy written for adults is merely a variation of mainstream fiction with elements of romance, intrigue, mystery, suspense, horror, sagas, and more. In this genre, the focus of the novel is not on solving a mystery, but on the thrill of the chase. The Saga genre also enjoys a tradition of a family taking on a dream of freedom and follows that dream throughout several generations. While the police must solve crimes within the rules of the police department, the PI operates within their personal code of integrity.
Historical fiction uses history as the setting for the novel's action.
Aspects of most other genres are incorporated into the historical fiction category as a means of developing the plot of the story. The cozy mystery genre is typical Agatha Christie or Diane Mott Davidson. This formula features an amateur detective in a domestic crime in a small population, such as a small town or country manor.
