Our Lady of Guadalupe inspires millions of believers, offering a mothering balm of love, peace, and forgiveness through her Blessed Son. Read the legend of the appearance of the Holy Mother on Tepeyac Hill near Mexico City. Her apparition was witnessed by Juan Diego who had gone to the hill at the request of his Bishop to gather roses for the church. The Bishop’s actions were inspired by a request for a sign from the Holy Mother after she asked the Bishop to build a church on the hill. When Juan Diego returned with the roses, an image of the Holy Mother was embedded in his tilga–a garment that has remained without any sign of wear or age for the last 485 years.
Miracles do happen but we never know how or sometimes why. The universe and the Earth herself are imbued with numinous qualities that we intuit but can never “prove”.
In my novel Threshold, Dolores Olivarez is a devout Catholic who recites the Rosary as she hikes the mountain to the top.
At the summit, she looks out over the vast metropolis, and then down at the Birthplace of Tucson at the base of the mountain. 
From a place of reverence, Dolores seeks to understand the meaning of her time and place, much as Juan Diego climbed to gather his roses.
