When investigative journalist Hana Sinclair uncovers a cryptic reference to an ancient botanical manuscript left to by her late grandfather, she unravels a thread tied to Hildegard von Bingen, a 12th-century abbess, healer, and mystic. Her findings reveal that Hildegard’s work holds more than historical value—it may conceal the key to curing some of humanity’s most devastating diseases. But someone is determined to ensure her secrets stay buried.
As Hana teams up with Father Michael Dominic, prefect of the Vatican Secret Archives, and Marcus Russo, a Vatican archaeologist, they discover that a powerful biotech corporation, Zentara, has been systematically suppressing cancer cures for profit. Zentara’s reach is vast, its operatives ruthless, and its agenda clear: control the narrative of medical progress at any cost.
The team races to uncover and protect Hildegard’s work, their journey taking them from Geneva to Rupertsberg Abbey, where Hildegard lived and worked, to Zentara’s high-tech laboratories. Along the way, they face betrayal, danger, and the weight of their own convictions. For Hana, the fight becomes deeply personal, challenging her notions of justice and the role of science in society.
But when Zentara accelerates its plans and begins human trials with catastrophic consequences, the stakes grow even higher. Can the team expose the corporation’s crimes, safeguard Hildegard’s legacy, and ensure her healing vision is not lost to history?
