Desert Prophets is a genre hybrid combining the historical family saga and saga fiction.
According to author Bill Smith, "The family saga is a genre of literature which chronicles the lives and doings of a family or a number of related or interconnected families over a period of time… this is often a thematic device used to portray particular historical events, changes of social circumstances, or the ebb and flow of fortunes from a multitude of perspectives." According to the online encyclopedia, Wiki, "An essential element of historical fiction is that it is set in the past and pays attention to the manners, social conditions and other details of the period depicted.”
Saga fiction includes multiple generations and includes dramatic events told with thick and rich descriptive narrative.
