A Miracle in Mexico is #97 in the Camfield series and was published in September 1991. Orina Vandeholt is the richest American girl and prey to every fortune hunter! She flees New York for a cruise to Mexico where she is kidnapped by an Englishman who is helping the native Mexicans bring water to their region.
We see in this cover by Fiord Forlag, our couple standing near a great waterfall. Note the native people in the background. Our hero is dressed like them, but the heroine wears a pink gown more suitable for a city! We get the impression that there is more between them than the discovery of water!
