As noted above, many different themes are presented in realistic fiction. Whatever the theme, it should arise naturally out of the story being told. The book should provide some insight into the problem being explored and how it might be resolved. Readers should be encouraged to draw their own conclusions about what happens in the book. Watch for books that seem didactic or preachy: “a book becomes didactic when the teaching function over powers the telling of a good story.” (Glazer, 418)
