Children of the lamp

Djinn twins John and Philippa are off on another whirlwind adventure that takes them around the globe and into unknown worlds. And it's a race against time as they attempt to rescue their mother from her fate as the Blue Djinn of Babylon. An aging curse has been placed on their father and if the twins are gone too long, he'll rapidly become an old man. Meanwhile, museums all over the world are reporting robberies of valuable jade from their collections, as well as bizarre hauntings.

Twelve-year-old twins Philippa and John have more adventures when they become involved in an international escapade involving the Blue Djinn, the supreme arbiter of all Djinn.

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.
