What are the motifs in Rachel's Tears: The Spiritual Journey of Columbine Martyr Rachel Scott by Beth Nimmo?

Rachel's father and brother travel around the country, encouraging youth to begin a chain reaction of kindness. They do this in Rachel's memory, based on a paper she wrote entitled "My Ethics, My Codes of Life." Rachel believed in the core values of trust, compassion, honesty, love, and the desire to believe the best about people. She believed that if one reached out to help someone else, it might inspire them to do kindness toward others.
