The book "I'm Standing on the Rock" is based on the author's childhood experiences in Las Vegas in the 1970s. It follows the story of a girl and her brother as they explore the desert, encounter wildlife, and witness an encounter between red ants and black ants. The story ends with the children singing a little song: "I'm standing on the Rock, I'm standing on the Rock, Jesus is my Savior, I'm standing on the Rock."
