The tale begins over three-hundred years ago, when the Fair People-the goblins, fairies, dragons, and other fabled and fantastic creatures of a dozen lands-fled the Old World for the New, seeking haven from the ways of Man. With them came their precious jewels: diamonds, rubies, emeralds, pearls... But then the Fair People vanished, taking with them their twelve fabulous treasures. And they remained hidden until now...Across North America, these twelve treasures, over ten-thousand dollars in precious jewels, are buried. The key to finding each can be found within the twelve full color paintings and verses of The Secret. Yet The Secret is much more than that.
