When former FBI agent Mike McClintock traded the streets of Chicago for a quiet vineyard in California's Santa Ynez Valley, he thought life would finally slow down. With his wife, Julie, and their two children, Mike is looking forward to nothing more than a carefree Caribbean cruise. His brother Jason-a successful geologist who struck gold in Montana-joins the family, along with their unlikely companions: Vladimir Petronovich, a reformed KGB operative, and Vasily Volkov, a thrill-seeking ex-SVR dive master. What begins as a long-overdue reunion quickly transforms into something far more perilous. A chance discovery of a centuries-old shipwreck off St. Maarten entangles them in a dangerous web of treasure, intrigue, and cartel interests. Bonds of loyalty and trust are tested as past allegiances collide with present threats. From sunlit vineyards to storm-tossed waters, Deadly Treasure is a high-stakes tale of family, friendship, and the treasures-and dangers-that lie hidden beneath the waves.
