What narrative structure (episodic plot, parallel plot, etc.) does the author use to tell Incidents in the life of a slave girl?

"Incidents in the Life of a Slave Girl" by Harriet Jacobs has a classic, conversational and realistic style in which the reader feels as if he were talking to the protagonist. The narration is simple and attractive as in "I was born a slave, but I never new it till six years of happy childhood has passed away". Another key stylistic feature is the directness when addressing the reader as in "Reader, did you ever rate? I hope not".
