What is the author's tone in Drinking: A Love Story by Caroline Knapp?

Knapp's tone is very open and honest throughout the entire novel. Because it is a memoir, she is not only being honest with the reader, she is also telling the truth for herself. The reader can tell that Knapp's open, frank tone has allowed her to almost come clean in a sense. She holds nothing back about her strained relationship with her father, her unfaithfulness to the men in her life, her battle with anorexia, and her father's adultery. She also reveals her own deep, carnal fears that haunted her and led to her eventual alcoholism.
