The Poison Keeper - Deborah Swift

Naples 1633

Aqua Tofana - One drop to heal. Three drops to kill.

Giulia Tofana longs for more responsibility in her mother's apothecary business, but Mamma has always been secretive and refuses to tell her the hidden keys to her success. But the day Mamma is arrested for the poisoning of the powerful Duke de Verdi, Giulia is shocked to uncover the darker side of her trade.

Giulia must run for her life, and escapes to Naples, under the shadow of Mount Vesuvius, to the home of her Aunt Isabetta, a famous courtesan. But when Giulia hears that her mother has been executed, and the cruel manner of her death, she swears she will wreak revenge on the Duke de Verdi.

The trouble is, Naples is in the grip of Domenico, the Duke's brother, who controls the city with the 'Camorra', the mafia. Worse, her Aunt Isabetta, under his thrall, insists that she should be consort to him.

Based on the legendary life of Giulia Tofana, this is a story of hidden family secrets, and how courage and love can overcome vengeance.
