Book 1

THE SEVEN KEYS OF HILDEGARD
​​Of Mercy & Of Death

In 1167, a German nun has a troubling vision, prophesizing the end times. In 1917, Mary appears to three children in Fatima, Portugal, revealing mysterious secrets. In 1936, a young man is inexplicably hurled to his death off the side of a mountain in Italy, and the newborn he unknowingly leaves behind is spirited away to America by his terrified mother. But why?

Tackling events throughout the early 20th century, The Seven Keys of Hildegard: Of Mercy & Of Death will challenge the very truth of what the church and the world knows. Through two world wars, and from the Vatican in Rome, Italy, to New York City and small town Canada, two knowing popes, an unsuspecting archbishop and a monsignor become entangled in Hildegard’s ancient web of prophecies. And one thing is certain—Armageddon is nigh.

I'm not Catholic, nor religious but I guess I am spiritual. But let me tell you, I couldn't put this book down! It had me totally engrossed, a page turner. Then to find that it's half true and happening in our times. Wow. I didn't expect that. Amazing story. Can't wait for book 2 and the rest of the series to find out how the church, and the world fares. You have a gift and weave a great story. You're onto something and big!

I could not put this book down. it's a classic "good vs evil" story that combines fact, fiction, religion, history and suspense that kept me reading faster just to get to the next page. David's ability to take the reader from the past to the future and back and forth from one continent to another is literary magic and his knowledge of religious history is amazing. I can't wait for book 2 of this thrilling saga.

Book 2

THE SEVEN KEYS OF HILDEGARD
Of Love & Of Betrayal

In 1167, a German nun named Hildegard, has seven troubling visions of the end times. In 1958, the new pope, John XXIII, begins his reign and must decide how to make his church relevant in a rapidly changing and increasingly dangerous world of the 1960s and 70s. In this second book of David Dupuis’ thrilling five-part historical-fiction series, the ancient battle lines are drawn.

​From a convent in Fatima, Portugal, to a hut in Africa, the halls of the Vatican, office towers in New York City to a small town in Canada, the ancient Keys inevitably turn. Through it all, a mother’s devotion to her child and those who protect them are threatened. Can the church and world be saved from political, economic, military and spiritual assassinations? With evil lurking in the halls of power, only two things are certain. Where there is love—there is always betrayal.

I enjoyed how many local connections there were in this book. As someone who lives in the same town as the author I was so excited to see those local connections. David makes the religious histories easy to read and understand. I could not put this down and in fact read it in 3 weeks which only leaves you wanting more. I can't wait until the third book.

Okay, David. M. Dupuis, you've officially hooked me. Somehow, The Seven Keys of Hildegard: Of Love and of Betrayal took me on a journey of self-discovery. I would rate this series of books up there with the DaVinci Code. Definitely one for the ages! I'm bracing myself for all the twists and turns I'm sure we are in store for in Book 3.
- SUZANNE D.
Captivating book of historical fiction and suspense. Second one in a series. Again a great and quick read. Thank you David for writing these.
