What is the author's style in Foreign Affairs by Alison Lurie?

Foreign Affairs is narrated consistently in a detached third person, present-tense voice, primarily as description of people, places and events. However, long passages of dialog are often included. Flashbacks to childhood memories are generally narrated in the past tense, linked to a present action or emotion. The change in verb tense from present to past indicates that a character is remembering something that happened previously.
