The submarine U-5001 was a Nazi secret weapon that could have changed the course of World War II. Kapitaenleutnant Erich Heinz Bruckner commanded the U-boat on its only mission-a voyage that transported him and his crew to a place of wonder...and horror.
Dexter McCauley is a present-day ex-Navy diver who finds the only evidence of the U-5001's existence, which drives him to discover its original, terrifying mission.
Submerged follows both men in a narrative that spans generations, echoing the tales of Lovecraft at their most strange. As the paths of these men's lives converge, a third element surfaces to influence their decisions-decisions that will shape the future of civilization in ways never imagined.
