Whats the authors tone ? read the following introduction for a research paper on novels and answer the question.

the word novel is borrowed from the italian word novella (henry 235). defining exactly what a novel is can be hard work. the standard dictionary definition is "a fictional prose narrative of considerable length, typically having a plot that is unfolded by the actions, speech, and thoughts of the characters" ("novel"). novels in some way represent life. the representations, however, occur in a narrative about life and experience. since the novel can represent life, such fiction can be serious. the seriousness begins when the novel deals with humankind in a way that shows its importance and significance within the fictional world of the novel. the world of a novel varies greatly from author to author because each writer creates a new fictional world for a new work. that world may be all the relationships of a whole nation or of a very small town. that world may be as confined as the captain's cabin on a ship or as open as a little island. that world may also be as withdrawn as the farthest recesses of the human mind. novels are important as they entertain and instruct the readers through a variety of life experiences.
