Aboard the USS Kingfish in the Sea of Japan, a secret mission unexpectedly becomes life threatening. After the dyed-in-the-wool Naval Commander, Joe Camissa, begrudgingly accepts a short-fused mission, he finds himself dangling 20 feet above the deck of a North Korean military vessel-while inside a half-ton atmospheric diving suit (ADS).

Following the mission, Camissa and his crew are left with several unanswered questions. Amidst the struggles of a severe brain injury and a disintegrating marriage, a series of strange events unfold as the unwilling hero walks down the slippery slope of espionage and betrayal.

Rich with detailed, accurate, and technical information, this gripping military "fact-ional" thriller shows the depths of darkness acquired after three decades of service. Commander Camissa, who was once a young, idealistic sailor, must do whatever it takes to seek justice and protect his country.
