Four "swabbies" arrive at a military base in the Philippines, ready to assume active duty aboard the U.S.S. Tunny, a submarine specially configured to execute covert operations along the coast of Vietnam. Commander Browne, the Tunny's formidable skipper, soon reveals their mission: the infiltration of hostile waters. Their destination is one of the most heavily guarded harbors in the world. Those in Peril traces the lives of these brave men from their first trip down the sub's ladder to action on the banks of the Red River. Huddled together in the submarine's close quarters, the crew of the Tunny forms a bond that withstands ever-present danger, lost love and the horror of death. Based on a true story, Those in Peril is a coming of age tale of courage, told by one of the Vietnam War's own. "Clandestine submarine operations were our game and 'Tunny Tigers' was our name. We lived it and we loved it." -Mike Burkholder, former U.S.S. Tunny engineman "This gripping story could only be told by someone who was really there." -Lieutenant Colonel Joseph W. Hoffler, U.S.A.F. (ret.) "Those in Peril is a tribute to the courage and sacrifice of men who live day-to-day on the threshold of danger. Hunt describes in detail the trust and camaraderie that develops among men who share the unforgettable experience of war." -Capt. Edward M. Brittingham USN (ret.), author of The Iranian Deception
