Used book – Barrage sur le Nil, Christian Jacq

A monster. A cold, gray monster, 42 million cubic meters in size. A monster that threatens Egypt and its monuments with a slow but certain death. Such is the High Dam of Aswan, against which American Egyptologist Mark Walker has been fighting for years. The discovery of a very ancient prophecy foretelling a cataclysm prompts him to redouble his efforts just as he is about to get married. But his fiancée falls victim to an attack... Mark Walker's world then plunges into extremist violence which, like the dam, threatens to destroy Egypt. Tossed by the waves of a revolution underway, manipulated by shadowy figures, refusing to be blinded by love, Mark Walker relentlessly searches for the truth that is being hidden from him. A truth he has only thirty days to uncover if he wants to save Egypt.
