The Map of Love
Ahdaf Soueif
In 1900 Lady Anna Winterbourne travels to Egypt where she falls in love with Sharif, and Egyptian Nationalist utterly committed to his country's cause.
A hundred years later, Isabel Parkman, an American divorcee and a descendant of Anna and Sharif, goes to Egypt, taking with her an old family trunk, inside which are found notebooks and journals which reveal Anna and Sharif's secret.
