Book cover of The Twelfth Imam

Luana Ehrlich Author Of One Night in Tehran: A Titus Ray Thriller

From my list on international espionage intertwined with faith.

Why am I passionate about this?

I was eleven years old when I read my first adult spy novel. I was only able to get my hands on it after receiving permission from my father, who brought home three to four espionage books from the library every week. By the time I was halfway through the book, I was hooked on the genre forever. Since faith plays an important role in my life, I’m always delighted to discover authors whose books reflect a strong belief system yet who can tell a compelling, action-packed adventure without sounding preachy.

Luana's book list on international espionage intertwined with faith

Luana Ehrlich Why did Luana love this book?

I love thrillers that make me think, keep me on the edge of my seat, and put me in the very center of the action. This book did all of these and more.

This book is the first book in a three-book series by an author who is well-qualified to write about the Middle East and the threat Iran poses to Israel. Rosenberg speaks regularly with both Israeli and American government officials, and one of the things I enjoyed most about this book was the knowledge I gained about Iran’s nuclear capabilities, information that I couldn’t read in a newspaper. In addition, his protagonist is a man of faith, which I found very inspiring.

Luana's book list on international espionage intertwined with faith

Luana Ehrlich Why did Luana love this book?

I love thrillers with in-depth character development and realistic situations involving clandestine operations, and this book hits both of those marks.

This is the first book in a three-book series featuring the Mossad, the Israeli foreign intelligence service. I’ve always been fascinated by books that give me a behind-the-scenes look at how an intel agency operates and the tech gadgets that make the business of spying possible, and these authors describe both extremely well while giving me insights into how a Messianic Jew lives out his faith.

Luana's book list on international espionage intertwined with faith

Luana Ehrlich Why did Luana love this book?

I love thrillers that tell the story of a group of operatives who must work together under the leadership of a strong central figure in order to accomplish a difficult mission, and from the opening chapter, I knew this novel would be exactly that.

This is the first book in the Warrior Spy Thriller Series. While I thoroughly enjoyed getting to know the hero of the story, Delta Force operator, Reagan Rainey, who is temporarily assigned to a CIA entity, I was also fascinated by the other members of his special ops team, not only because of their unique personalities, but also by the way Rainey was able to share his faith with them without sounding preachy and to remind me of how grateful I am to live in America.

Luana's book list on international espionage intertwined with faith

Luana Ehrlich Why did Luana love this book?

I love thrillers that teach me about the culture of the Middle East, but it’s rare to find a novel that also includes how Christianity can be shared with such cultures. However, both of these are present in this novel, which is what makes the story so enjoyable.

This is book one in the Marc Royce Thriller Series and features intel officer, Marc Royce who’s sent on a secret mission to Iraq. Since I don’t like too much description in a novel, I admire Davis Bunn’s ability to portray the setting in this story, while not neglecting the characters and dialogue. There’s also a faith element to the narrative, which adds a lot of depth to the plot.

By Davis Bunn,

What is this book about?

Marc Royce works for the State Department on special assignments, most of them rather routine, until two CIA operatives go missing in Iraq--kidnapped by Taliban forces bent on generating chaos in the region. Two others also drop out of sight--a high-placed Iraqi civilian and an American woman providing humanitarian aid. Are the disappearances linked? Rumors circulate in a whirl of misinformation.

Marc must unravel the truth in a covert operation requiring utmost secrecy--from both the Americans and the insurgents. But even more secret than the undercover operation is the underground dialogue taking place between sworn enemies. Will the ultimate Reconciler…


Book cover of Masque

Christina Baehr Author Of Wormwood Abbey

From my list on gaslamp heroines with tea and adventures.

Why am I passionate about this?

I grew up surrounded by a library of dusty vintage novels, so perhaps it wasn’t that surprising that I went on to write my own gaslamp fantasy influenced by English folklore and Victorian heroines. I love historical novels that provoke wonder, and magical novels that are rich with history, and (blame it on being an only child?) most of all I love a female protagonist I’d want to have tea with.

Christina's book list on gaslamp heroines with tea and adventures

Christina Baehr Why did Christina love this book?

Isabella Farrah is one of the funniest, most exasperating leading ladies in literature. I was surprised and delighted by this loose retelling of Beauty and the Beast with murder, cake, pretty dresses, magic, intrigue, and Isabella’s hilarious brand of ladylike mayhem.

I would probably choke on my cake laughing if I ever had tea with Isabella (and maybe she’d slip something into my tea), but it would be worth it.

Book cover of Memoirs of an Invisible Man

Christopher Andrews Author Of Paranormals

From my list on putting a different spin on a popular genre.

Why am I passionate about this?

I absolutely love stories—books; TV shows; movies—that take a familiar topic, and either turn it on its ear or examine its full potential. For me, The Empire Strikes Back is one of the best sequels of all time because it did not just repeat what Star Wars did before it, but expanded upon it. As a reader, I seek this; as a writer, I emulate this. If a superhuman can produce kinetic shockwaves, what else might one do with this ability? If a vampire can turn into mist, what are the furthest implications of this supernatural skill? Don’t settle for a trope, explore it!

Christopher's book list on putting a different spin on a popular genre

Christopher Andrews Why did Christopher love this book?

I was floored by this fantastic thriller. Most “invisible man” stories cast the invisible character as the villain, but Memoirs flips the script, and the result is magnificent. The protagonist, Nick, is the victim of a scientific accident, and must go on the run from the corrupt government agents who want to capture him. The result demonstrates that Nick missed his true calling—he should have been a secret agent himself. Saint’s protagonist is clever and resourceful as he navigates through every attempt to trap him. And the best part of this different take on the genre: It leaves you asking yourself, “What would I do?” I’ve read it three times, and I spend the intervening years wondering how I would have survived in Nick's shoes. An absolute must-read.

Book cover of Summerland

Tone Milazzo Author Of The Faith Machine

From my list on spies in strange places.

Why am I passionate about this?

Spies are everywhere across the panorama of fictional tropes, in fantasy, science fiction, horror, and historical fiction. Spies are like salt. No matter the genre, drop a little espionage into the mix, and it tastes better. There’s an inherent complexity to a spy, a dichotomy baked into the profession, simultaneously a criminal and an agent of the government. A spy could be a one-man-army, a smooth-talker, or someone inside your computer network, but no matter who they really are, they’re never who they seem. The spy plays with identity, loyalty, and integrity in ways that the worst of us do but is safely compartmentalized in fiction for our enjoyment.

Tone's book list on spies in strange places

Tone Milazzo Why did Tone love this book?

If you’ve chafed at the limitations of scale by these suggestions, this is the book for you.

All the stories on this list, including my own, take pains to couch the supernatural in such a way that the political, social, and economical natural orders are not threatened by the introduction of speculative elements. Not in Summerland.

Their pseudo-science real, Victorian spiritualists find a way to the afterlife and back. Within decades the strange, alien city on the other side is flooded with the principles of industry, commerce, and espionage.

Taking place between the World Wars, the existence of Summerland, and the technologies that unfold from its discovery change the landscape of pre-World War II Europe, but not the inevitability of human nature.

Book cover of The Entity: Five Centuries of Secret Vatican Espionage

Stefan Vucak Author Of All the Evils

From my list on Christianity and its tortuous origins.

Why am I passionate about this?

Religion, faith, and belief are very personal things that can invoke powerful emotional and intellectual responses. Responses are shaped by social conditioning during childhood that can last a lifetime, engendering spiritual comfort or deep disturbance in adulthood. I began to question my Catholic indoctrination as I started to delve into historical accounts of early Christianity and the evils inflicted on the world under the banner of doing God’s work, politics waged by the Vatican to maintain secular power, distilling it all into something I finally felt comfortable with. 

Stefan's book list on Christianity and its tortuous origins

Stefan Vucak Why did Stefan love this book?

Fascinated by the Roman Catholic Church and its internal organization, many years ago, I naively assumed the Vatican was the world’s center of piety and righteousness and the guardian of the world’s morality. This book helped me shed a stark light on reality.

I never knew that from the 16th century, the Church maintained a secret service, the Holy Alliance, that meddled in every aspect of European politics. In 1930, they were renamed ‘The Entity,’ with its counterespionage arm, the Sodalitium Pianum, and the Vatican had its CIA. Once I started, I couldn’t put this book down, shaking my head. Laundering money for the Mafia, helping Nazi officers escape to South America, funding revolutions, assassinating those who stood in their way…This work blew me away and left me stunned and much wiser.

1 author picked The Entity as one of their favorite books, and they share why you should read it.

What is this book about?

For five centuries, the Vatican - the oldest organization in the world, maker of kings and shaper of history - has used a secret spy service, called the Holy Alliance, or later the Entity, to carry out its will. Forty popes have relied on it to carry out their policies. It has played a hitherto invisible role confronting de-Christianisations and schisms, revolutions and dictators, colonisations and expulsions, persecutions and attacks, civil wars and world wars, assassinations and kidnappings.For the first time in English (already a bestseller in Spain and France), Eric Frattini tells the comprehensive tale of this sacred secret…


Book cover of 355

Jerry Aylward Author Of The Scarlet Oak: Murder, Spies, and Spirits

From my list on historical time travel mystery.

Why am I passionate about this?

Like many others, and perhaps mostly the dreamers, I’ve had a lifelong fascination with time travel, along as many others, always wondering, what if? Plus, I have a passion for American history, mostly American Revolution history, always thinking, what if you could time travel back in time to witness history in the making, or travel to the future and witness the results of decisions made today. Plus, I have an obsession with a good mystery, mainly murder mysteries. I thoroughly enjoy a good murder mystery that has (I didn’t see that coming) twists, turns, and a few good red herrings. Which you can see by the books on my list. 

Jerry's book list on historical time travel mystery

Jerry Aylward Why did Jerry love this book?

If you enjoy historical fiction, American Revolution nonfiction, mysteries, and spies, you’ll love this book.

This is by far one of my favorite novels. The code # 355 which was historically used by General George Washington’s the Culper Spy Ring to identify an unknown female spy is marked in mystery to this very day. It held my undivided attention throughout because I’m from Long Island where the Culper Spy ring operated during the revolution, I was never disappointed with the story of 355.

Book cover of London Rules

Robert Craven Author Of A Kind of Drowning

From my list on spies, spying and cold war thrillers.

Why am I passionate about this?

I am the author of six espionage books, 5 featuring allied spy, Eva Molenaar operating at the highest levels of Hitler’s Reich. The 6th The Road of a Thousand Tigers, is my homage to le Carre and Ian Fleming. I have loved the spy genre since I first read The Riddle of the Sands by Erskine Childers and grew up seeing every Bond movie since The Man with the Golden Gun at the cinema.

Robert's book list on spies, spying and cold war thrillers

Robert Craven Why did Robert love this book?

This book certainly made me stop and think about how I write, and I have altered my style since. Set in modern-day London, the Slow Horses (failed MI6 operatives forced to work in Slough House) under the tutelage of Jackson Lamb eke out a futile existence. The heads of MI6 hope the demeaning work will make them walk away and leave the espionage world. Lamb is one of the great characterizations, a burnt-out spy who still has acres of tradecraft and protects his team against the outside forces at a political and international level. A string of random terrorist attacks around the UK seem to tie in with a show-boating politician riding the Brexit wave and the team goes rogue to find out the connection. A book as far away from Bond as possible but brilliantly written and plotted.
