Secret of the Loch

After briefly eluding Yassir Ali's ruthless assassins in England, Nick, Marie, and Ishi have fled north, where they hope to track down a forgotten cavern in the Highlands of Scotland. The cavern is linked to the Ambrosius Amulet, and is said to contain the greatest treasure of gold, jewels, and other artifacts ever amassed by the ancient druids....

Relying on Marie's memory of landmarks and coordinates given by her father, the task of searching Loch Ness, Loch Lomond, and Loch Morar quickly becomes a hazardous affair. Will one of these famed locations prove to be home to this fabled treasure of the early Brits? Or, will this be one myth that can't be solved, either by fate or bullets from a ruthless enemy closing in?
