Berengere, daughter of King

"Aren't you going to tell me I'm the daughter of a king, Wennael? "The proud Duke of Rochelyse with his wild sloes smiles without answering the sweet Berengère, his fiancée. Bérengère, a foundling child, attracted the implacable hatred of Catherine de Médicis, Queen of France. For what reason? The girl ignores it. The Duke, on the other hand, knows the secret of Berengère's birth. When she's his wife, he'll know how to protect her.
He decided to marry her without delay in his castle of Ménez-Run. She accepts, madly in love.... Unfortunately, one day, when Bérengère accidentally entered the castle's underground, she surprised her beloved husband, who was busy with a sinister and cruel task. A vigilante's work, no doubt. But will Bérengère be able to forget this unknown and terrible Wennael, glimpsed in the dark depths of Ménez-Run?
