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

Living life to the fullest is the main theme of the book. Rachel was known for her passion for life. From a very young age, she seemed to know that she wouldn't live a very long life. When she was young, she never played house like other children. In her journals, less than a year before she died, she commented that it would be her last year of life. This could have been why she embraced life and Christianity the way she did.
