Watercolorist Olivia Rutherford has shed her humble beginnings to fashion her image as an avant-garde artist to appeal to the region's wealthy art-collectors. When she lands a lucrative contract painting illustrations of Yosemite National Park for a travel magazine, including its nightly one-of-a-kind Firefall event, she hopes the money will lift her and her sisters out of poverty. After false accusations cost him everything, former minister Clark Johnson has found purpose as a backcountry guide in this natural cathedral of granite and trees. Now he's faced with the opportunity to become a National Parks Ranger, but is it his true calling? As Clark opens Olivia's eyes to the wonders of Yosemite, she discovers that people are as vital to the park's story as its vistas-a revelation that may bring her charade to an end.
