Book excerpt: History claims she is the first female serial killer. Locusta is the daughter of a winemaker in the Roman province of Gaul. She enjoys the indulged childhood of the elite, her concerns only about the day’s amusements. She rides gentle ponies, attends parties, reads Ovid, and learns the herbal arts from her servant. But the day after meeting her betrothed, Locusta discovers the consequences of possessing such dangerous knowledge. Ordered to leave her pastoral life, Locusta is thrust into a world of intrigue, scandal, and murder—where treason lurks behind every corner and defying an emperor means death. Locusta’s life changes forever when a young Emperor Nero requires her herbal expertise and commands her to be his personal poisoner. Caught in an imperial web, Locusta must embrace her profession or die. Or is there another way out?
