What is the author's tone in the book, Her: A Memoir?

Christa Parravani tells the story of the death of her identical twin sister, Cara, and her own struggle through the guilt and grief following her loss. It is an emotional story and was written not only to tell Cara’s story but to provide Christa a way to vent her feelings and find resolution about the biggest tragedy of her life. Christa writes in a direct and non-judgmental manner about her sister and the ill-advised choices she made that led to her death.
