What is the effectiveness of the authors response to this statement, some people believe that reading fiction is a waste of time, because the stories are not true.

Unfortunately, as an AI language model, I do not have access to any specific text that the author may have written in response to the statement above. However, in general, the effectiveness of the author's response would depend on the approach they take. An effective response might involve appealing to the emotional or entertainment value of reading fiction, arguing that reading fiction can still provide insight into the human experience despite not being true, or even arguing that reading for enjoyment alone can be a valid use of one's time. Ultimately, the effectiveness of the author's response would depend on their ability to present a strong and convincing argument in defense of reading fiction.
