Djinn twins John and Philippa are off on another enchanting, and dangerous, adventure in the last book in the bestselling Children of the Lamp series. As volcanoes begin erupting all over the world, spilling golden lava, the twins must go on a hunt for the wicked djinn who wants to rob the grave of the great Genghis Khan. Can the twins stop this latest disaster before the world is overwhelmed? Join John and Philippa, their parents, Edward and Layla Gaunt, Uncle Nimrod, and Groanin as they must defeat an evil more powerful than any they've ever faced before.
Overall, this book is about the twin's final adventure. It is extremely sad to the devout readers at the end. So, to the point. John and Philippa are off on their sixth adventure, traveling around the world when a series of volcanic eruptions started to go off. Even extinct volcanos, and dormant ones are blowing up with golden lava. So they must find the Hotaniya or Dragon crystals in the tomb of Ghengis Khan.
