Drowned History — Rebecca Lovell

Their love was supposed to last forever, but Alice Graesser's disappearance more than ten years earlier drove a cold wedge between her and her lover, George Bennett. In the fall of 1940, the search for an ancient Indian artifact with the power to change their lives brings them back together. Their expedition seems straightforward at first but they soon discover that they've never encountered anything that remotely prepares them for what they find, both inside the cave and out, where the past comes back to haunt and the future is a drowned dream. Can Alice and George find what they lost, or will the power that draws them toward the ancient treasure tear them apart for good?
