Twelve-year-old Sarah is finally in charge. At last, she can spend her summer months reading her favorite science books and bossing around her younger brother, Ellis, instead of being worked to the bone by their overly strict grandmother, Mrs. Greene. But when their cousin, Janie arrives for a visit, Sarah's plans are completely squashed.

Janie has a knack for getting into trouble and asks Sarah to take her to Creek Church: a landmark of their small town that she heard was haunted. It's also off-limits. Janie's sticky fingers lead Sarah, Ellis and his best friend, Jasper, to uncover a deep-seated part of the town's past. With a bit of luck, this foursome will heal the place they call home and the people within it they call family.
