A baby is born with a coin in her hand. An orphan crafts a mysterious wooden object. The CEO of a large corporation finds himself under extraordinary pressure at work and at home. And on a remote hilltop on a Caribbean island, a medicine man seems to understand the meaning of all these events and to hold the key to the future.

Montaro Caine, CEO of the Fitzer Corporation, is losing control of the company he built just as his teenage daughter is experiencing her own difficulties. At this moment of crisis, a man and woman appear at his office with a coin of unknown provenance, composed of a metal unknown on Earth. Montaro immediately recognizes it as the companion of a coin he analyzed as a graduate student working in a lab at MIT, which was later returned to its unidentified owner. The coin's appearance draws the attention of scientists, collectors, financiers, and thieves, all of whom vie to get their hands on it, and Montaro himself hopes that the discovery of the coin will save his company.

But the value of the coin lies not in its monetary worth but in its hold on the people who come into contact with it. These include the young woman who is not aware of the object that was found in her hand at birth; an old man who, as a boy, crafted a wooden compact as a gift for a young Montaro Caine; and the elusive healer Matthew Perch, who, from his hut on a small Caribbean island, knows precisely why these people have been brought together and what wisdom the coin imparts.
