When a strange girl follows twelve-year-old Delta Wells and her younger brother, Jax, to Hilton Head Island after a visit to a Savannah pirate festival, the sibling duo suspects that time is playing tricks on them again. Who is this mysterious person, who is she fated to become, and how can they return her to her own era before she gets stuck in the twenty-first century forever? On their adventure to find the answers, the kids learn about the dangers of water pollution and what they-and readers-can do to help save our oceans.
Like its predecessors, the fourth book in the award-winning Delta and Jax mystery series will charm readers of all ages with its blend of real history, a touch of magic, and an inspiring message about the Sea Island environment.
