What is the author's style in The Iron Heel by Jack London?

The language used in both the story and the commentary is very much tied to the point of view of their writers. Specifically, Avis "writes" with the almost poetic, at times melodramatic, at times intensely romantic language of the passionate devotee - in her case, to her ideals and to her husband. Her language is that of someone who knows that s/he is writing for posterity, with the idea of leaving behind both historical documentation and interpretation / idealization of that documentation. In other words, her language is self-conscious, self-dramatizing, and often self-indulgent.
