John and Philippa Gaunt, two twelve-year-old not-very-identical twins, live a privileged life in the Upper East of Manhattan with their wealthy parents and two curiously-mannered Rottweilers named Alan and Neil. The twins realise something amiss with their world when strange things begin to happen after their wisdom teeth are extracted--they dream the same dreams, become more robust, their zits clear up, and wishes inexplicably in their presence come true. And, when their estranged Uncle Nimrod asks them to go to England for the summer during one such shared dream, the discovery of their destiny is set in motion. John and Phillippa discover that they are descended from a long line of Djinn and have great inherent powers. They must call on these powers sooner than they anticipated, though, because the ancient Egyptian pharaoh Akhenaten is not as dead as history has declared, and his legion of seventy magical djinns could tip the balance of power in the supernatural realm and affect the whole world order.
