Big Red by Douglas C. Waller

A good submarine book about the Nebraska, a Trident missile sub and its captain and crew. Mostly about people and the mission and some about the boat. About living on board, stress on family, and the jobs and aspirations. Amazingly complex, quite dangerous, constant drills keep things on edge. Even the skipper is constantly being tested. A sub travels thousands of miles blind, just listening to avoid colliding with something. A scary thought.
