If you told Sloane Osburn and Amelia Miller-Poe that theyd 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, theyd have been sure you got your facts wrong. Finally, if you told them theyd be doing all of this as friendswell, they would have been sure you needed medical attention.

Whether through serendipity (really, really good luck) or zemblanity (really, really bad luck), someone tricked their teacher into using their seventh-grade class to investigate the mystery of their towns long-missing treasure. From there, things have escalated. Quickly. Now, the girls are stuck hiding behind a gravestone, dodging acorns (who knew acorns could be so threatening?), and just a few clues short of those jewels.

Its 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
