The Sea Witch's Revenge

What begins as a fun night of sharing ghost stories in a local graveyard soon turns sour when twelve-year-old Delta, her younger brother, Jax, and their friends are falsely accused of vandalizing a historic site on Hilton Head Island. When the siblings start receiving centuries-old messages via a mysterious wooden box they find at the Island History Museum, they must do double duty as they strive to prove their own innocence while wrestling with an even tougher problem from their island's past. Can Delta and Jax actually change history, and, perhaps more important, should they?
