In 17th century France where women have virtually no rights or legal protection, the Church is all-powerful and determined to root out heresy and witchcraft wherever it can find it.
For one young girl, unwilling to take vows of chastity and obedience, and preparing to leave the Convent of Montmartre, life is about to become doubly dangerous.

1659
Alone at 15 years old, Elisabeth Osborne is beautiful, naive and easy prey as she fancies she can manage on her own in Paris, but a chance meeting with the madam of a gentlemen's club changes her mind. It is here she receives protection, the sort of education not taught in convents and, just as important, the freedom to practise her skill with herbal remedies without fear.

But it isn't only her unusual knowledge of plants and the workings of the body which might land her in danger. In times of stress, she is capable of extraordinary feats which she cannot always control and which she struggles to keep secret.

She doesn't know her mother's English family or who her father is - and she doesn't know why she's able to see and do things others can't. She sets out to find answers, travelling to Brittany and across to England where London is gripped by plague and fire.

But is she prepared for the answers? That’s the question…
