In his 31st novel in the Jesse McDermitt Caribbean Adventure saga, Stinnett once more unites old characters with new, mixing cutting-edge technology with history in a tale of untold wealth, greed, and conflict. The once pristine waters of Everglades National Park are being looted once more. Invasive pythons have taken over as the top predator. Water levels have dropped to an all-time low to maintain the agricultural industry. And a rusting hulk has been lying undiscovered for eighty years. Until Billy Rainwater stumbled upon it. After several years, mountains of paperwork, and a healthy dose of South Florida “good ol’ boy” palm-greasing, Billy and his two closest friends, Jesse McDermitt and Rusty Thurman, have begun the tedious recovery of the U-320, a World War II Nazi submarine, which had been driven deep into the Glades by a great hurricane. A fortune in Nazi gold is at stake, and the trio of long-time friends and adventure seekers don’t know they’re sitting on it until it’s almost too late. At the same time, but on a different front, evil stalks a middle schooler and Jesse has to find a way to bring the man to the kind of justice Jesse's known for. Can the wealth of a great city be recovered and returned? Or will it sink into the muck along with the instruments of war which brought it? The stakes rise exponentially as lives are threatened, and the tranquil waters of South Florida once more erupt into chaotic violence.
