The twelve-year-old tomboy Bitsy travels to Hilton Head Island, South Carolina, where she expects sun, fun, and a baseball trophy, but as usual, things never quite work out as she expects. It's bad enough that she has to move in with strangers and that her baseball glove is missing, but the problems don't end there--Bitsy and her new friends, Cole and Mallory, discover a loggerhead turtle thief is on the loose. The robber could be right under their noses. As Bitsy tracks down a criminal and tries to lead her team to victory, she begins to learn the truth about lies.
