    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.

  • 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 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?

  • The Sea Turtle’s Curse: A Delta and Jax Mystery

    The white turtle shone pink in the watercolor light of the sunset, and she let her finger gently trace the intricate honeycomb carving on the animal’s back. Everything happened so gradually that she didn’t notice at first that the turtle was becoming warmer or that the pink cast had become a rosy glow. She didn’t even notice that fog had rolled in and surrounded her feet. In fact, Delta didn’t notice these changes at all until the mysterious fog had entirely engulfed her. She stood in the haze still clutching the now-blazing red turtle.

    Twelve-year-old Delta and her younger brother, Jax, have no idea of the excitement in store when they discover a mysterious carved turtle figurine on the beaches of Hilton Head Island, South Carolina. But when the kids become disaster magnets, they realize that their new treasure has magical powers they’d never imagined! Along with their new friend, Darius, the siblings uncover forgotten American history and learn the importance of passing on stories as they travel throughout the Carolina Lowcountry—and time itself—in a race to break the turtle’s curse before a hurricane destroys their island home!
