What is the author's tone in the nonfiction book, A Mother’s Reckoning?

As the memoir was written sixteen years after the tragedy at Columbine High School, the tone reflects the author's years of consideration and reflection over the events. At the heart of the book, the author expresses her desire to share a full picture of her son, and emphasis his death as a suicide. The author is clear in stating that her intent is not to pardon her son for his actions in any way but instead she hopes that her writings will shine a light that will help other parents truly see their children and get them help if needed. Due to this, the tone is full of sorrow, pain and a consistent stress to educate oneself on the many pressing issues she covers. It is her goal, therefore, to challenge readers to look at the world from a different perspective, and understand that most tragedies are in fact, preventable. Overall, the tone of the book is diverse, shifting from remarkable sadness and sorrow to optimism and passionate advocacy.
