The Lake of Learning

Cassiopeia Vitt has spent over a decade constructing an authentic 13th-century French castle when an ancient book of hours is discovered at her site, unveiling connections to the once-prominent Cathar sect. This historical community once thrived in southern France until they were declared heretics and nearly exterminated in the early 13th century. The newfound artifact ignites a perilous race involving a thief and a billionaire, each intent on uncovering the Cathars' most prized secret. As Cassiopeia navigates this treacherous landscape, she becomes entangled in a chilling rivalry marked by revenge and murder.
