What is the author's style in We Drink the Wine in France by Alice Walker?

In Walker's We Drink the Wine in France, the story is told in the third person, through two alternating perspectives. Each section after the first one alternates the perspective from which the story is being told and thus gives insight into that character. The perspective switches back and forth between the old weary French professor and his youthful student Harriet. Even though there are no major physical interactions between the two main characters, by knowing both characters' thoughts and dreams, one knows that inwardly there is a connection.
