The Children of the Lamp Series
by P.B. Kerr (Author)
John and Phillipa Gaunt are 12-year-old twins. Ordinary human children, they believe, until the discovery that they're actually descended from a long line of djinn - commonly known as genies - and are now in possession of great magical powers.
But djinn-magic is tricky and dangerous, and their new-found skills must be controlled. Fortunately, their eccentric uncle, Nimrod is on hand to teach them. All too soon, however, John and Phillipa are thrown into the first of their many extraordinary adventures. Travelling to far-reaching and unknown places in the world, the twins use their wits and magic powers to prevent disaster, solve mysteries and battle the plans of evil djinns.
