A Ship Possessed takes place off the coastal shore of California and the main character of the book is a ship, the USS Triggerfish. The Triggerfish was a submarine that disappeared back in World War II…but is now back, fifty years later! The arrival of the submarine is full of mystery. What happened to it and where was it for all those years? Better yet, why has it returned? These are the questions J.D. Stanton, a retired Navy captain, is asking. But as he begins his investigation, he is drawn into a whole new world that involves the spiritual; something that Stanton has never encountered before.
