The Emersons' journals chronicling the 1907-8 season have been discovered, revealing hitherto unknown events from Amelia Peabody's remarkable career! Banned from the Valley of the Kings, their excavation at an abrupt end, Amelia and her distinguished husband, Emerson, have returned to England with their son, Ramses, and foster daughter, Nefret. Ramses is secretly in love with Nefret and about to flee to Germany to escape temptation. But a mysterious visitor provokes a change in plans for Ramses and the others. After a decade without contact, Prince Tarek from the Lost Oasis has written to the Emersons, asking for help. His only surviving son is ill, and his throne may be threatened . . . Guided by only a crumbling map that took them to the Oasis a decade earlier, the Peabody-Emerson clan head for the Sudan. There they confront forces secretly arrayed against them; there Ramses must face up to his feelings for Nefret.
