After purchasing a rare book at an estate sale, thirty-three year Chicago trader Brad Mason finds something rather remarkable within its pages: a hidden reference to a lost treasure from a Spanish galleon sunk off the southwestern coast of Florida in 1733. Three of his best friends, Max, George, and Lou, convince Brad to seize the opportunity to have a little adventure, and after making the necessary arrangements, the four travel to Florida. A rickety old boat, scuba diving equipment, and the promise of gold doubloons in their hands is all the four need to get started. It's not long before they discover the wrecked Spanish ship and even some buried treasure. But they're not alone in their quest for fame and fortune. A band of cutthroat pirates wants the treasure as well, and they'll stop at nothing to get their hands on it. Pretty soon, the four friends are playing a game of cat and mouse. When Max and George are kidnapped, Brad and Lou have no choice but to save their friends even if it means losing the treasure! Found! The Lost Treasure Ship San de Cristo delivers an action-packed story of intrigue, danger, and adventure!.
