Synopsis

The third installment in the Martin McMillan middle grade mystery series (ages 9-13) find finds thirteen-year-old skateboarders Martin McMillan and his friend Isabel on a vacation in Scotland, drawn into another exciting adventure. Gaelic verses, recently found in the lining of an old trunk, hold the key to Druid secrets on the windswept Isle of Lewis. Clues lead to the ancient Calanais Standing Stones, which rival the wonder of Stonehenge. Martin and Isabel are determined to uncover the truth before other, less scrupulous parties can beat them to it. But dark forces go to great lengths to keep the island’s secrets from the outside world.
