Huntington's works include the novel Carfrae's Comedy, the play Barton's Folly, and the bestselling book Madame Solario.
From a young age, she lived in New York, Paris, London, Biarritz, Rome, and "a villa on Lake Como.
The novel was anonymously published in 1956 (likely due to what was considered scandalous content), and her identity as the author would not be revealed for three decades.
It is mainly thanks to the French journalist and novelist Bernard Cohen, who investigated in 2009, that Huntington was recognized as Madame Solario's author.
After her death, Huntington left behind a manuscript of a play entitled The Ladies’ Mile (dating from 1944), which she had planned to adapt into a novel.
