Mitch Crawford stumbled across his first find as a college student and together with his partner, went on to earn worldwide fame as they discovered, and salvaged, a dozen more treasure ships. But Mitch crossed the wrong man at the wrong time, and now that man is out to bring Treasure Seekers to its knees.

In time, they travel from the turquoise seas of the Caribbean, to the historical center of Seville, Spain, and spend many a romantic eve on Robert's Foe. But can they find their way to the most important treasure of all—their love—in the midst of fending off an enemy willing to do anything it takes to beat them? It all happens Once Upon a Caribbean Summer...
