The Hildegard Seeds

Vatican Secret Archive Thrillers, Book 10

By: Gary McAvoy

Narrated by: Will Damron

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?

A gripping tale of courage, faith, and the pursuit of truth, The Hildegard Seeds explores the timeless struggle between greed and the greater good, weaving historical intrigue with modern-day suspense in a story that will resonate long after the final tick.

Fabulous Story....

..... that is an instrument of education and provides an opportunity to think about one's own moral, ethical and theological beliefs and actions. I want to know more about her and listen to her music. I am pretty sure I would have enjoyed knowing her.

Fascinating

Such a great book, I love how the author blends historical facts with fiction. Many times after listening to Gary McAvoy’s books I wish history had gone this way, but never say never. Highly recommend this book and all of Gary McAvoy’s books.

Another sit on the edge of your seat story!

As his other books Gary McAvoy didn’t disappoint! Full of intrigue, adventure, and combined with the human elements both good and bad. Can’t wait to start the next one!

Micheal’s decision.

I love all of Father Micheal and Hannah books and their friends. Great series! Thanks!

Very intriguing

I loved this book taking me down the path of an amazing woman whose talent in understanding plants in the 11th century blows the mind. Yes this is a fiction but it’s based on the REAL Hildegard. The author does such justice to her but weaves an interesting thrilling story. At the end he goes into detail who she was in real life and how he found her story. The narration was very well done and kept me sitting in my car to listen for what happens next. Read it you won’t be disappointed
