From the remote villages of Afghanistan to the depths of the ocean, Lieutenant Commander Grant Chisolm is on a mission to thwart jihadists. His latest assignment as liaison officer to Guantanamo brings him face to face with the Taliban and Al-Qaeda, and their hatred of the United States, once more. Dive into the explosive world of terrorism and those fearless enough to fight it in Killing Sharks. "In the best tradition of the works of Frederick Forsyth and Dan Brown, Killing Sharks: De Profundis is a thriller that takes the reader from the desolate mountains of the FATA on the Afghan-Pakistani border to the warm waters of the Caribbean and the base prison at Guantanamo, Cuba. Navy SEAL, Lieutenant Commander Grant Chisolm, races against the timing of suicide bombers and through the murky world of the modern war on terrorism and the backwaters of the Cold War. Wentz's work is authentic. It's the product of a navy officer who has seen Guantanamo and the world-wide war on terror firsthand." Dr. Ralph L. DeFalco III, Senior Strategist, Joint and Coalition Warfighter Support, Under Secretary of Defense for Intelligence, Captain, USNR
