In memory of this period, she wrote a book Oppéde published in French and in English by the editor Brentano in New York. This book was lately published by Gallimard. On request of Saint Exupéry she joined him in New York, where they both enjoyed a fashionable and artistic life, but she was increasingly disturbed by Saint Exupéry's violent desire to join his unit.

In 1944, the aviator and writer disappeared; he had just finished writing his master piece, le Petit Prince. In the book he had imagined his wife as a Rose. She remained in New-York hoping for his return and writing him letters every Sunday.

In 1945, at the end of the war, she left the United States to settle in France living in Paris and in Grasse.She met regularly Salvador Dali and Picasso and during all these years, she increasingly expressed her career as a sculptor and a painter. She also spent a lot of time perpetuating her husband memories. As the Comtesse of Antoine de Saint Exupéry, widow of the great writer, who gave his life for France, she attended inaugurations, commemorations, and celebrations.

Consuelo Suncin Sandoval, Comtesse Antoine de Saint Exupéry had a prestigious French name, but today her artistic personality deserves to be recognized. Her paintings as well as her memories are full of the colours and the violence of that Salvadorean land she loved more than anything else.

When we look at her paintings we discover that the sources of her inspiration were often borrowed to the culture of Central America and the interplay of colours evoked the generosity of a blazing land of volcanos .Her painting is the incarnation of the art of an era, the reflection of a passionate land and finds its inspiration in love, esteem, and respect to the man who had given her his name.

Consuelo de Saint Exupéry died in Grasse in 1979; she rests in the cemetery of Pere Lachaise in Paris.
