For 131 years the eight-man crew of the H.L. Hunley submarine lay in their watery grave, undiscovered. When the sub was finally raised, there was no indication the blast had breached the hull, and all eight men were still seated at their stations. So why did it sink? Why did the men die? In the Waves is the story of Rachel Lance's single-minded obsession as she attempts to unravel the story of the Hunley. A gripping mix of original research and a story of professional and private obstacles, In the Waves is an enthralling look at a unique part of the Civil War and scientific rigour.
