The Burning Chambers | Kate Mosse

Carcassonne 1562. Nineteen-year-old Minou Joubert receives an anonymous letter at her father’s bookshop. Sealed with a distinctive family crest, it contains just five words: SHE KNOWS THAT YOU LIVE.

But before Minou can decipher the mysterious message, a chance encounter with a young Huguenot convert, Piet Reydon, changes her destiny forever. For Piet has a dangerous mission of his own, and he will need Minou’s help if he is to get out of La Cité alive . . .
