The seven cities of gold have remained hidden behind a veil of the earth’s electromagnetic field for thousands of years. Scientist Rock Wilson developed a way to detect the magnetic abnormalities that connect our world to the ancient world. On a scientific expedition, Rock Wilson disappears into the hidden ancient realm.

His eleven-year-old daughter, Brett Wilson, armed with his old field book and equipped with the mystical Cross of De Soto finds a bridge between the two connected lands. Brett enters the veiled world to find that the forces that hold it together are diminishing. The elders send Brett and her friend Natalie on a quest to find the ancient knowledge of the people, the Well of De Leon. She will need her father if she ever hopes to find the Well and set things right.
