The Sea Witch's Revenge
A Delta & Jax Mystery

What begins as a fun night of sharing ghost stories in a local graveyard soon turns sour when 12-year-old Delta, her younger brother Jax, and their friends are falsely accused of vandalizing a historic site on Hilton Head Island, South Carolina. 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?
