Man's eternal quest for gold proves as enduring as it is fatal when forensic archaeologist Lindsay Chamberlain unearths a four-hundred-year-old mystery—and a modern-day murder. Vacationing in Tennessee, Lindsay studies the bones of a centuries-old corpse hiding a fascinating secret. She's also asked to look into the suspicious deaths of two adventurous cavers whose fatal foray into Hell's Slide spells murder for one family member.

But bones don't lie, and before long, Lindsay knows she's digging up trouble. Someone wants the case to remain closed—and the mounting threats tell her she's getting closer to the truth. But as murder old and new come together in shocking ways, Lindsay finds herself digging for her life—to survive the clever trap of a killer.
