What is the author's style in A Spell for Chameleon by Piers Anthony?

A Spell for Chameleon was written in 1977. Although the time frame for the story is undefined, the language is clear, contemporary, and easily understandable for teens and adults. Characters engage each other through plain American English, and would be easily understandable if they were to converse with readers. The use of contemporary language helps to move the plot easily and quickly, as readers are not forced to analyze passages as the plot progresses.
