About this book
What if a pirate’s buried gold draws you out of comfort and into a rivalry of hearts?
Francis Morgan is young and wealthy, with an easy life and a name that carries a pirate’s shadow. The legend of the buccaneer Henry Morgan promises hidden gold. It pulls Francis toward a dangerous search, alongside another Henry Morgan, a man bound to him by family history.
In Hearts of Three, Jack London sends the treasure hunters through Caribbean ports and into the dense jungles of Central America. Small boats, physical hardship and narrow escapes keep the quest moving. Leoncia brings love and rivalry into the hunt, so buried riches are not the only thing that matters.

A rich loafer is lured toward pirate gold
The story opens in a New York mansion on Riverside Drive. Francis Morgan, heir to his father's millions, lounges in his library and worries only about getting soft. He tells nervous friends to hold on to their shares in Tampico Petroleum, a Mexican oil company that holds most of his fortune.
What he does not know is that Thomas Regan, an old partner of his father, is quietly buying those shares and spreading doubt. He pays a visitor named Alvarez Torres to tell Francis of the buried treasure of Sir Henry Morgan, the buccaneer ancestor, then pretends to scoff at the tale.
