John and Philippa Gaunt are all ready for their lives to return to normal now that their mother has given up her djinn powers. But the siblings are quickly drawn into yet another mystery when the world's luck tips wildly out of balance (to the world's detriment). The key to the world's fate lies with five fakirs who were buried alive, each of whom guards a secret that can answer a great question of the universe. But there's an evil djinn desperate to dig up the secrets. Without their mother's powerful magic, John and Philippa must face this djinn alone.
While traveling around the globe, from London, to Morocco, to Yellowstone National Park, to the snowy Himalayan peaks of Shangri-La, can the twins harness their own powers to defeat a new evil?
