When seventh grade enemies research a missing set of jewels for a class project, they realize that the answers to the unsolved case might be much closer to home than they thought.

If you told Sloane Osburn and Amelia Miller-Poe that they'd be hiding in their town cemetery from an evil mastermind, they would have been hard-pressed to believe you. If you also told them that person was intent on beating them to a cache of long-lost jewels using nothing more than a slingshot and wicked aim, they'd have been sure you got your facts wrong. Finally, if you told them they'd be doing this as friends . . . well, they would have been sure you needed medical attention.

Whether through serendipity or zemblanity, someone tricked their teacher into using their seventh-grade class to investigate the mystery of their town's long-missing treasure. From there, things have escalated. Now, the girls are stuck hiding behind a gravestone, dodging acorns, and just a few clues short of those jewels.

It's up to these enemies-turned-partners to uncover centuries-old clues to find the treasure at the end of this book before the mysterious person on their trail can get to it first . . .
