Walter Link and Miriam Wollaeger, a young geologist couple in 1920s Wisconsin, set out to find oil to supply the surging U.S. demand. This exciting work will allow them to build their lives in South and Central America, Indonesia, and Cuba. But from the first posting in Columbia, they quickly discover that no women are working in the field in these places. While Walter faces the hardships and thrills of exploration in the jungles and mountains, and eventually becomes chief geologist for Standard Oil, Miriam is left behind in the colonial capitals during Walter’s often lengthy times away. She defines herself through the limited means left to a woman within their small societies: playing bridge or polo by day and dancing into the wee hours with early KLM pilots, diplomats, and the footloose sons of moneyed Americans and the European aristocracies. She also raises three children, has intimate involvements, learns the local languages, and takes up teaching. But she is not satisfied. And finally she does something about it.
