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.

Reviews of BOOK 1 "Of Mercy & Of Death"
​

The writing is imaginative, effective and clear, the themes well developed. Vivid imagery adds depth to the narrative. The settings are well-described, conveying both time and place. In particular, the descriptions of the Vatican are vivid, with its talk of visions, revelations, popes and secret keepers, as is the arrival of a new Patriarch to Venice. An ambitious, complex and interesting story.

I normally am not a big fan of historical fiction but let me tell you, I didn’t mind it this time! This book was pulling me in. There is this intense sense of urgency the entire time that something bad is coming and they must do everything they can to prepare for it.
The characters are well developed, and the book stays interesting by jumping back and forth from different time periods as well as places around the world. It took a whole new turn on good vs evil and there is so much more to explore as this is only the first book in a series. I will definitely be continuing the series as I finally found a historical fiction that doesn’t bore me to tears.

David Dupuis has gone where few tread in his historical novel series, "The Seven Keys of Hildegard." This series takes the reader into a Catholic world Hildegard would have known well - a world of politics, betrayal, superstition, seduction, prophesy and ritual - a world existing somewhere deep within the "fallen stars" struggling to get back to the Light. His historical novel series is a page-turner and pulls out a piece of Hildegard's charism not well-known. I loved how the author wove together so many historical nuggets into the fictional text. His love for Hildegard and church history shine through. Looking forward to reading Book Two!

A great story with history, secret societies and the Church - the battle between good and evil! This first book of a five-book series left me anxiously awaiting the release of Book 2 so i can learn what happens next!
- GOODREADS READER KATIE O. Barrie, Ont.

I'm not Catholic, nor religious but let me tell you, I could not put this book down! I must be spiritual because it had me totally engrossed, a real page turner. Then to find that it's half true and happening in our times. Wow! I didn't expect that. An amazing story. Can't wait for book 2 and the rest of the series to find out how the church, and the world fares. The author has a gift and weaves a great story. Definitely onto something and big!
- ROBERT T. Toronto, Ont. Canada
A very good read in the DaVinci Code genre. A mystery in the world of Catholicism. Loved identifying with Pope Pius. People the world over fascinated with the events of Fatima. I found the writing was excellent and kept my interest from page 1. Would appeal to anyone who likes a good mystery with a Canadian connection.
– AMAZON.CA READER Waterloo, Ont. 
One of the best novels I’ve ever read! I couldn't put this book down. The use of historical facts combined with the intriguing fictional storyline keeps the reader wanting more! It reads like a combination of Thorn Birds and the DaVinci Code. I cannot wait for Book 2!
- SANDRA N. Kitchener, Ont.
I couldn't 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.

Reviews of BOOK 2 "Of Love & Of Betrayal"
​

Like I have said many times before, historical fiction has never really been my thing. But David's first book actually intrigued me and gave me a little bit of a liking for the genre. So now in his second book, I can say that the little bit of love is still there as I enjoyed this one too. I think I liked this one because you already knew a lot of the characters because one of my issues with the first one was that there were a lot of characters to keep track of and it was a bit hard for me to keep up but now that they have been fostered into my mind, this book went a lot smoother. I can also see how the author wanted to build anticipation for that big ending.

Some of the relationships seemed a little forced but others were very heartwarming and had me invested. These books deal with family a lot and I do like that about them. Having a caring and supportive family is really nice to see in a book. I will definitely read the rest of the books in this series when they come out.
- ERIK McMANUS, Breakeven Book Reviews 
I read the first two volumes and thoroughly enjoyed the exciting adventure of the classic, dualistic battle between good and evil in the context of this apocalyptic peeling away of the layers of history. I loved the way the author presented his characters in a narrative reflection on the developments and issues faced by the Church in the modern world. He highlights very clearly the Church’s holiness and the hellish temptations that face so many in the Church.
​I lived in Rome during Paul VI’s funeral, John Paul I’s election and month-long pontificate, and was in St. Peter's Square for the announcement of John Paul II's election and the first few years of his pontificate. These books brought back many memories and clearly highlighted so many key concerns faced by our world and the Church. I wait eagerly for coming volumes. I would love some day to see this story on the big screen!
- Fr. PETE MIHALIC, Fairport Harbor, Ohio. USA​
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.
- JOHN Z. Penetanguishene, Ont.
Captivating book of historical fiction and suspense. Second one in a series. Again a great and quick read. Thank you for writing these.
- DENIS D. Windsor, Ont.​
Waited for this second book of the 5 novel series, and ordered it right away! OMG!! It just gets better and better!! The use of historical facts to create this suspense filled storyline, had me on the edge of my seat!! Like the first book, I couldn't put this second novel down!
- SANDRA N. Kitchener, Ont.
WOW! This story has everything. It has suspense, intrigue, love, evil, the battle between good and bad, fact, fiction, history, prophecy and it never stops moving. From Rome to rural Canada to New York to Africa and across multiple centuries and into the future. What an amazing story.
- DON M. Midland, Ont.
A hybrid of ‘Pillars of The Earth’ and 'The Thornbirds.' ​A fascinating historical timeline told through the filter of Good vs Evil. This book reveals the blemishes and the warts of the Vatican yet allows the reader to root for the hero who has a predestined future within it.
- ROGER D. Mexico
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.
