One Thanksgiving afternoon at his grandparents'' house, Jordan Salama discovers a large binder stuffed with yellowing papers and old photographs - a five-hundred-year wandering history of his Arab-Jewish family, from Moorish Spain to Ottoman Syria to Argentina and beyond. One story in particular captures his attention: that of his great-grandfather, a Syrian-born, Arabic-speaking Jewish immigrant to Argentina who in the 1920s worked as a traveling salesman in the Andes - and may have left behind forgotten descendants along the way. Encouraged by his grandfather, Jordan goes in search of these ''Lost Salamas,'' traveling more than a thousand miles up the spine of South America''s greatest mountain range. Combining travelog, history, memoir, and reportage, Stranger in the Desert transports readers from the lonely plains of Patagonia to the breathtaking altiplano of the high Andes; from the old Jewish quarter of Damascus to today''s vibrant neighbourhoods of Buenos Aires. It is also a fervent journey of self-discovery as Salama grapples with his own Jewish, Arab, and Latin American identities, interrogating the stories families tell themselves, and to what end.
