This epic World War II saga follows the USS Squalus and Sculpin as they play out their dramatic destinies in the Pacific. The author, a seasoned journalist, re-creates their entire perilous journey. The Squalus sank during a test dive in 1939, but thirty-three trapped crewmen were saved. The Sculpin's role in that rescue is just the first of many incongruous twists of fate that brought the two subs together.
