The crisp mountain air invigorated Clara as she hiked along the winding trail. The world seemed brighter, more vibrant than usual. A constant current of well-being hummed beneath her skin. Reaching a clearing, she sat down to take in the breathtaking view, when a folded piece of paper caught her eye. It was a clipping from a local bookstore, advertising a book signing. The title read, "The Mountain Muse: A Journey of Finding Clarity." The book described her life. A surprised laugh escaped her, a sound that echoed her delight, her sense of wonder.
