Secret Place of Thunder: Book 5

Cheney and her nurse, Shiloh Irons, visit Cheney's great-aunts at their indigo plantation outside of New Orleans. They arrive to discover that a mysterious malady has been inflicting the servants and sharecroppers, and that the indigo crop is suffering as well. All evidence appears to point to a cult of spiritism that has claimed that the plantation is on sacred ground and that the aunts must leave. When Cheney and her family begin to investigate, they face physical danger as well as spiritual threats.
