Setting
This has readers describing the location as important, often in terms of details about daily life wherever or whenever. Readers will talk about the place (rather than the people). This will be a cross genre appeal characteristic, for example some people will only enjoy historical crime novels (perhaps only ones featuring actual historic characters in a fictional setting, or only romances set in the middle ages or earlier).
Some works written about other times and other places, whether historical or imagined (speculative fiction) will include setting as a important doorway with speculative fiction there are also setting preferences. Some people may only like fantasy set in recognisable locations (such as Sean William’s works set in South Australia). Authors who have setting as a dominant appeal characteristic include Tim Winton, Alastair Reynolds and Ellis Peters.
