Four young friends Nate, Summer, Trevor, and Pigeon meet the grandmotherly Mrs. White, owner of the Sweet Tooth, and soon learn about the magical side effects of her candies. Rock candy that makes you weightless. Jawbreakers that make you unbreakable. Chocolate balls that make you a master of disguise.
In addition, the ice cream truck driver, Mr. Stott, has arrived with a few enchanted sweets of his own. But what about the mysterious man in the dark overcoat and fedora hat? Why are all these "magicians" trying to recruit Nate and his friends? Who should they trust?
The mystery deepens and the danger unfolds as the four youngsters discover that the magical strangers have all come to town in search of a legendary, hidden treasure one that could be used for great evil if it fell into the wrong hands. The kids, now in over their heads, must try to retrieve the treasure first. And so, the war begins . . ."
