When thirteen-year-old Delta Wells arrives on Hilton Head Island, South Carolina to visit her grandparents, she anticipates the usual peaceful summer of seaside fun. When she learns that Pops’ beloved Island History Museum will likely be replaced by a new golf resort, though, and then discovers a skeleton hidden in the marsh on the museum property, she suspects that this summer will be like no other. A long-secret message from the past sends Delta and her younger brother, Jax, on a quest to unearth the island’s secrets, save their grandfather’s museum, and help complete a task begun on Hilton Head more than 150 years ago in the shadow of the Civil War.
