Discovery of the Tomb for an Unknown Egyptian Princess

This novella begins around 1970 at the LaRoches' farm in a small French-speaking village called Sainte Riviere hidden behind the hills above Lake Geneva, Switzerland.
At seventeen, Ariane learns her true identity during a visit from a stranger. Her whole life, as she has known it, is turned upside down.
Six years later, she graduates from the University of Geneva with a degree in archaeology.
The prospect of helping her father and his team to possibly discover an important tomb is irresistible. She works at the Narhami excavation site in a deserted valley in Upper Egypt. The tomb turns out to be that of an unknown Egyptian princess who married a king from Nubia.
During these months, Ariane not only finds ancient royal treasures but much more.
