When four cousins, Tess, Grant, Leo and seven-year-old Willa, are summoned to Joshua Tree National Park by ARGO, an advanced robotic Labrador Retriever, they must follow the clues to confront a billionaire CEO at the Coachella Music Festival before A.V.A.R.I.A., the powerful corporate AI, can stop them.

Mysteries on the road, science in the story, honor when no one is watching.

A family-friendly techno-thriller for ages 8 to 80, with 142 illustrations, 74 infographics and 15 Brain-Builders. Real science on groundwater, solar power, AI and water from desert air is woven into the adventure, along with seven classical virtues, the Seven Quiet Powers.

A note on AI: The story was written over eight months by the author, a retired software engineer with more than 50 years of experience. AI tools were used to help create the illustrations, cover and audiobook narration, and assisted with some dialogue.
