The Knights of the Cornerstone

Calvin Bryson has hidden himself away from the world, losing himself in his work and his collection of rare and quirky books. He never meant to let so much time go by without visiting his aunt and uncle in the tiny town of New Cyprus, California. When he gets there, he'll discover the town's strange secrets and a mysterious group dedicated to preserving and protecting holy relics―a modern-day incarnation of the legendary Knights Templar.
