Meet John and Philippa Gaunt, twelve-year-old twins who one day discover themselves to be descended from a long line of djinn. All of a sudden, they have the power to grant wishes, travel to extraordinary places, and make people and objects disappear. Luckily, the twins are introduced to their eccentric djinn-uncle Nimrod, who will teach them how to harness their newly found power.

And not a moment too soon . . since John and Philippa are about to embark on a search to locate a monstrous pharaoh named Akhenaten and his eerie tomb.
