The Lake of Learning

About the book

For more than ten years, Cassiopeia Vitt has been constructing a genuine French castle using only materials and techniques dating back to the 13th century. However, the discovery of a treasure - an ancient Book of Hours - at the construction site raises numerous questions, all of which lead to an ancient and forgotten religious group.

At one time, the Cathars thrived throughout southern France, challenging the authority of Rome and attracting tens of thousands of followers. In 1208, the Pope labeled them as heretics and initiated a crusade - the first instance of Christians killing other Christians - resulting in the massacre of thousands and the near extinction of the Cathars. Now, a piece of this history has resurfaced, revealing the location of the most precious possession of the Cathars. As a thief and a billionaire express interest in this secret, a race ensues.

From the medieval walled city of Carcassonne to the mysterious Montségur peak and a hidden cave beneath the Pyrenees, Cassiopeia finds herself entangled in a conflict between two individuals consumed by vengeance and murder.
