As summer begins to wane, the Bartletts leave the lakeside community of Wolfhollow, New Hampshire to take a last minute vacation to the seashore. A half mile from the beach sits Mystery Island. This fog-enshrouded island happens to be the destination on a pirate treasure map the kids recently discovered. However, to find the buried treasure, Fourteen-year-old Leah Bartlett and her two siblings, twelve-year-old Avery, and nine-year-old Grayson must decipher a secret code. Along the way they meet new friends, encounter rough seas, and uncover a treasure that is different from anything they could possibly imagine.
