Autumn, 1919. At last, the Great War is over. McCracken and his family are safe to take a vacation on the Nile, hoping to see their friend Cristofero Campo di Serpenti the archaeologist. But the calm waters of the Nile seem more and more deceptive, as the McCrackens encounter Egyptian revolutionaries, find themselves trapped in an underwater tomb, captured by Bedouin tribesmen, chasing international jewel thieves, and facing the dangers of the Sahara Desert. In this latest McCracken adventure, you will find yourself catapulted into a world of ancient and mysterious ruins, singing sand dunes, mythological creatures and, above all, the elusive lost oasis, land of wonder and riches beyond imagining . . .
