What is the main conflict in High Tide in Tucson: Essays from Now or Never by Barbara Kingsolver?

High Tide in Tucson by Barbara Kingsolver is a collection of twenty-five of the author's essays. The subjects contained in her anthology range from the tough times she experienced as an egghead in high school in her small town in Kentucky to her work as a successful writer. One common thread that touches the diverse subjects that she addresses in this collection is her passion—her passion for literature, societal issues, her family, community, animal and plant conservation and of the care and welfare of her daughter, Camille.
