In Scotland in the spring of 1296, a ragged band of Templars seek refuge for a gravely wounded seneschal, a high-ranking Templar officer. As England invades Scotland, the Templars devise a dangerous plan to prevent the destruction of the H?ling, a collection of priceless Celtic treasures, manuscripts, and masterpieces. As the mysterious Lord Eagan travels with his companions-and his wyvern, a tiny magical creature-to fetch the H?ling, Adam, a thirteen-year-old Templar squire, finds himself in the midst of the intrigue. He is chosen to carry a crucial message to set the plan in motion, and his older sister, Hanna, jumps at the chance to trade her mundane life for a more precarious fate. But only integrity, noble character, and discretion will save the H?ling from ruin. In this historical novel, set in thirteenth-century Scotland, a young Templar squire and his sister set out on a quest to protect Celtic knowledge and treasures from dark forces.
