“McAvoy wants to educate and show the reader how much we don’t know, which he does through the guise of using Father Michael Dominic’s curiosities for all things historically Christian. There is nothing like a McAvoy story to leave the reader with many questions, as they flip to the back to see just how much is fact and where McAvoy uses creative freedoms.” (The Jerusalem Scrolls)

Attention to detail in depicting the Miscellanea and the Riserva and the archaic machinations of the Vatican is vastly appealing, offering the readership detailed inner knowledge into a little-known sanctum."

"The narrative clips along, fuelled by great storytelling and well-developed ideas that propel things forward with ease... There are also key learning moments that McAvoy uses to shed light on possible truths and deceptive use of fiction to keep the stories strong and wonderfully entertaining." (The Apostle Conspiracy)

“McAvoy weaves mystery and intellect like few other authors; if you like Dan Brown, you’ll love this. And he is certainly no lesser quality as an author; his attention to detail and writing proficiency are as good as it gets.”

"You may not be trying to “evangelize,” but in capturing both the good and bad found in our [Church’s] history you reveal the spirit of the faith in a nonconfrontational manner as you share enjoyment and encourage reseach. I taught high school history for over 30 years and would recommend your books to anyone who found history books boring. You teach as well as entertain.”
Deacon Robert PageSt. Patrick Catholic Church, Independence, Oregon
“This story brims with intrigue, danger, and the fight for a religion’s soul. Steeped in Vatican and WWII intrigue, this history-rich thriller will appeal to readers eager to unravel conspiracies and explore the past.”

“I feel that he has plenty of these globetrotting, swashbuckling, academic-based stories left in him; indeed, as many as there are priceless artefacts in the world.”

McAvoy's narrative structure is sound, and, true to his genre, he populates his thriller with characters engaging or villainous enough to serve the purposes of the plot . . .

McAvoy is a tremendously eloquent author of the utmost professionalism. His attention to detail is definitely a strong point, and he clearly carries out a huge amount of research into the technicalities and historical accuracies in his work.

“McAvoy has crafted a realistic plot that is full of historical and contemporary details. A great deal of research lays the foundation for the narrative. [The author] provides amazing descriptions of the settings and his writing style is captivating.”

“I stumbled upon the first book in this series last summer and could not put it down. When Gary McAvoy reached out to me to read the next two novels, I pushed all my other reading commitments to the side so that I could dive right in. I was thrilled and devoured the stories, as they tell such an alluring tale, so much so that I was up well into the night to flip pages and discover what was to come of the protagonists. McAvoy’s ability to spin a tale is second to none.”

“McAvoy’s plot melds art, music, and ciphers into a century-spanning, edge-of-your-seat heist. Historic and modern clues meld together perfectly, and the complex workings of church and mob hierarchies combined with character relationships elevate the story. McAvoy’s prose is both clear and direct, serving the story well. Clever dialogue and unique character voices make the novel shine even brighter.” (The Vivaldi Cipher)
The BookLife Prize
“The key to a strong thriller novel is whether the reader can feel themselves begin a part of the action, rather than a passive bystander. Gary McAvoy creates an electric buzz around his stories and puts the reader right in the middle of everything that is going on. His narrative builds with each passing chapter, developing more mysteries and curiosities, while the plot twists repeatedly to keep anyone from knowing exactly what will happen.”

"I can tell McAvoy has done an immense amount of research to make this novel as accurate as possible...I really like his precise descriptions of the Vatican and other aspects, such as restaurants, foods, gardens, etc. McAvoy also tells readers the historical facts upon which he built his novel. He is an intelligent writer and a stickler for details, from weapons to Vatican finances, and that makes reading his novels both entertaining and informative.”

“McAvoy is stellar in his delivery and peppers fact and fiction throughout, forcing the reader to pay close attention as they attempt to splice truth from fanciful dream. [He] does a sensational job in yet another thriller that is sure to leave the reader excited to see where things are going and exhausted from the journey found herein. Surely one of his best novels to date, which will keep series fans rushing back for more!” (The Jerusalem Scrolls)

The Voynich Codex

A Vatican Secret Archive Thriller - Book 11

In a discreet, exclusive auction house nestled within the historic streets of Bruges, Belgium, a mysterious artifact emerges—an ancient botanical manuscript known only as the Hesperides Codex. Believed to hold the key to finally deciphering the impenetrable secrets of the legendary Voynich Manuscript, the codex draws the attention of Vatican archivist Father Michael Dominic and investigative journalist Hana Sinclair. Their pursuit swiftly becomes a dangerous race across Europe’s shadowed corridors of power, forgotten monasteries, and ancient alchemical laboratories, as the hidden truths within the codex threaten to rewrite history itself.

Yet Michael and Hana soon realize they’re not alone in seeking these forbidden secrets. Ruthless biotech magnate Alton Blackthorn, obsessed with exploiting the manuscript’s enigmatic formulas, unleashes Christophe Vaux, a relentless operative determined to silence anyone standing in their path. Allies blur into adversaries, trust gives way to betrayal, and each breakthrough inches Michael and Hana closer to those who would kill to guard the manuscript’s explosive implications. With time running out and danger at every turn, their mentor Dr. Simon Ginzberg, an esteemed scholar haunted by his own complex past, proves essential to unraveling layers of deception and intrigue.

As their quest intensifies, Michael and Hana uncover the astonishing origin of the Hesperides Codex—a revelation not merely historical, but otherworldly. Facing forces desperate to suppress the truth, they must grapple with knowledge that could either illuminate humanity or plunge it into chaos. In a final, harrowing confrontation, they must decide whether the world is prepared to face the profound revelations hidden within the Hesperides Codex—and the unimaginable power locked within the Voynich Manuscript itself.
