What is the author's style in Under My Skin by Doris Lessing?

Lessing is a fiction writer, but the autobiography is firmly rooted in facts. There is a certain amount of discomfort evident when the author is required to explain to the reader the reasoning or logic behind her actions. With few exceptions, the author moves the story along without comment on her feelings. Those exceptions relate to communism, world politics, and the segregation issues of Africa.
