Some definitions of historical fiction state that the book needs to be set 25-50 years prior to when it is published and that most of the novel’s concept and background should be based on the author’s research of the time period. There is some debate over certain books, like To Kill a Mockingbird, which was published 24 years after the time period and The Grapes of Wrath, in which the characters represent “nameless thousands.” I have always considered both historical fiction. What do you think? Are there any books on my list that don’t fit the definition? Check out the links below for further discussion.
