Book cover of Killing Floor

Jody Summers Author Of A Brush With Death

From my list on romance, adventure, or a touch of the paranormal.

Why am I passionate about this?

I have been an avid reader all my life and have been fortunate (or unfortunate) to have a life full of a variety of experiences. Wonderful stuff to draw on when you’re writing, including a unique near-death experience. When I stumbled on a book idea with a topic I’d never heard of before, I was fascinated with the idea of writing “something new under the sun.” I also am thrilled to write books that give others as much joy as reading has given me over the years. A little action, a little passion, and a bunch of plot twists bring other worlds to life for me.

Jody's book list on romance, adventure, or a touch of the paranormal

Jody Summers Why did Jody love this book?

I picked this book because it is the 1st Jack Reacher novel, but they are all great. They speak to me because they depict a very unusual guy. A tough guy with a brain and a strong sense of right and wrong. A vagrant who fixes problems wherever he goes.

I have been accused of having a white-knight syndrome all my life, so I find this character riveting. Action, plot twists usually a touch of romance. These are all things that speak to me and Jack Reacher novels are full of them.

What is this book about?

Ex-military policeman Jack Reacher is a drifter. He's just passing through Margrave, Georgia, and in less than an hour, he's arrested for murder. Not much of a welcome. All Reacher knows is that he didn't kill anybody. At least not here. Not lately. But he doesn't stand a chance of convincing anyone. Not in Margrave, Georgia. Not a chance in hell.


Book cover of The Black Echo

John Klawitter Author Of Foul

From my list on strong men and women attempting survival in a less moral environment.

Why am I passionate about this?

I was a wild card in the industry heavy town where I was born and raised, destined to burn out my days early in a factory or steel mill. But I worked my way through college, survived several close calls in Vietnam and bull headed my way into a series of jobs that pushed me toward Hollywood assignments as a writer, producer and director.

John's book list on strong men and women attempting survival in a less moral environment

John Klawitter Why did John love this book?

I liked this novel because I was in Vietnam, have friends forever changed by contact with the mad god Mars, and could easily relate to the main character.

After his time in the military, Vietnam war tunnel rat Harry Bosch has to fight his own PTSD as well as very real present dangers in his job with the Los Angeles police force. Since I have studied the L.A. police for some of my novels, Connelly’s writing rings very true to me.

What is this book about?

An LAPD homicide detective must choose between justice and vengeance as he teams up with the FBI in this "thrilling" novel filled with mystery and adventure (New York Times Book Review).

For maverick LAPD homicide detective Harry Bosch, the body in the drainpipe at Mulholland Dam is more than another anonymous statistic. This one is personal . . . because the murdered man was a fellow Vietnam "tunnel rat" who had fought side by side with him in a hellish underground war. Now Bosch is about to relive the horror of Nam. From a dangerous maze of blind alleys…


Book cover of The Puzzle Palace: A Report On NSA, America's Most Secret Agency

Patrick D. Anderson Author Of Cypherpunk Ethics: Radical Ethics for the Digital Age

From my list on history surveillance techniques in the USA.

Why am I passionate about this?

I have always been suspicious of government and corporate power, but it was only when my officemate in graduate school started teaching me about digital technologies that I really focused on the power relations involved in institutionalized surveillance. Eventually, I discovered the cypherpunk movement, which opposes surveillance. I wanted to know what they knew, so I started to read everything I could about surveillance. I found that few journalists and almost no academics attended to the powerful message of the cypherpunks, so I decided that I would write the first academic book about the movement, hoping that I could do my part to raise awareness about this crucial issue. 

Patrick's book list on history surveillance techniques in the USA

Patrick D. Anderson Why did Patrick love this book?

I read Bamford’s work because I wanted to understand the history of the NSA, and I was not disappointed. I loved learning, in excruciating detail, about the surveillance techniques and programs of the NSA before the internet. 

This book shattered my impression that the NSA was a responsible agency that turned “bad” during the War on Terror. Bamford showed me that modern-day NSA mass surveillance, as revealed by Edward Snowden, actually represents the normal workings of the NSA rather than merely being an aberration. The most important lesson, though, was that the NSA has worked so hard to suppress the public use of encryption, the most important anti-surveillance technology we have.

Why should I read it?

3 authors picked The Puzzle Palace as one of their favorite books, and they share why you should read it.

What is this book about?

In this remarkable tour de force of investigative reporting, James Bamford exposes the inner workings of America's largest, most secretive, and arguably most intrusive intelligence agency. The NSA has long eluded public scrutiny, but The Puzzle Palace penetrates its vast network of power and unmasks the people who control it, often with shocking disregard for the law. With detailed information on the NSA's secret role in the Korean Airlines disaster, Iran-Contra, the first Gulf War, and other major world events of the 80s and 90s, this is a brilliant account of the use and abuse of technological espionage.


Elephant Safari

By Peter Riva,

Book cover of Elephant Safari

Peter Riva Author Of Kidnapped on Safari

New book alert!

Why am I passionate about this?

I have been to, and loved, North, Central, and especially East Africa for over fifty years. Only six times have I been to Africa on holiday; more often, perhaps twenty or more times, as a television producer. Working in Africa gains a perspective of reality that the glories of vacation do not. Each has its place, each its pitfalls like stalled plane rides with emergency landings in the bush or attacks by wildlife. But, in the end, the magic of the “otherness,” what an old friend called “primitava” captures one’s soul and changes your life.

What is my book about?

Keen to rekindle their love of East African wildlife adventures after years of filming, extreme dangers, and rescues, producer Pero Baltazar, safari guide Mbuno Waliangulu, and Nancy Breiton, camerawoman, undertake a filming walking adventure north of Lake Rudolf, crossing from Kenya into Ethiopia along the Omo River, following a herd of elephant making their annual migration.

Stumbling onto an elephant poaching, the team become embroiled in true financing of terrorism for al Shabaab –ivory sales–and are determined to stop the slaughter at any cost. Ivory trade financing terrorism involves UN refugee camps with two hundred thousand displaced Somali persons, powerful…

Keith's book list on spy books that will make you paranoid

Keith Thomson Why did Keith love this book?

Washington Post national security reporter Ignatius may not know the world of espionage better than anyone, but he writes about it better than anyone. Agents of Innocence is such a realistic and engaging depiction of the life of a CIA case officer that a copy of it is left in the room of each new arrival at Camp Peary, the CIA training facility. It’s about an idealistic young CIA officer posted to Beirut to penetrate the PLO, and, in the process, learns hard lessons, not least of which is that once human lives are at stake, idealism takes a back seat to pragmatism. Ultimately, it is a compelling story with terrific characters, and I would have rooted for them had they been accountants or fishmongers rather than spies

Keith Thomson Why did Keith love this book?

Ignatius’s most recent novel is in many respects a mashup of books no. 1 and 2 on this list: terrific storytelling and the latest spy recent tech: You’ll conclude that it’s just a matter of time until “bad actors” (spy speak for “bad guys”) can hack your brain. At the same time, you’ll enjoy the story.

What is this book about?

A hyper-fast quantum computer is the digital equivalent of a nuclear bomb; whoever possesses one will be able to shred any encryption and break any code in existence. The question is: who will build one first, the U.S. or China?

In this gripping thriller, U.S. quantum research labs are compromised by a suspected Chinese informant, inciting a mole hunt of history-altering proportions. CIA officer Harris Chang leads the charge, pursuing his target from Singapore to Mexico and beyond. Do the leaks expose real secrets, or are they false trails meant to deceive the Chinese? The answer forces Chang to question…

Keith Thomson Why did Keith love this book?

Exploding wine bottles, guns constructed out of pipes, bullets made of teeth, aspirin explosives: If these sound like props from a B spy movie, it's because, again, truth > fiction. In the early-1970s, the Central Intelligence Agency spent a great deal of effort developing myriad weapons for sabotage. The results were this seventy-two-page illustrated manual, published in 1977 and distributed to American operatives likely to find themselves in situations requiring such improvisation. The manual is also invaluable for writers.

DL Tolleson Author Of The Gray Stopgap

From my list on movie-ready thrills and good plots.

Why am I passionate about this?

In childhood, I memorized the Encyclopedia’s human anatomy pages, leading the family physician to explain, “Children like this become doctors or writers.” Good call, Doc! I wrote 14 of the 92 entries in my high school’s annual literary magazine (the most by one student). In college I earned a Bachelor’s, two Associates and Intercollegiate Press Association awards for Journalism and photography. I followed that with years of photography, photographic surveillance, 14 years of law firm litigation support, a temporary appointment as an SBA Paralegal Specialist, and 7 years of contract compliance at RadioShack headquarters. And, of course, my debut novel took 20 years of 8 drafts—I’m methodical that way.

DL's book list on movie-ready thrills and good plots

DL Tolleson Why did DL love this book?

I first read this book not because of interest—in fact, I hadn’t read anything else by its author, Robert Ludlum. Instead, I read this novel because I had been told that my writing was like that of Ludlum’s.

And that is startlingly true. It was as if reading something I had forgotten having written but which was richer with a depth of ever-increasing emotional nuances than works of a comparable kind. It’s a compelling read.

Through a combination of unusual story elements and narrative style, this novel engages a reader in the main character’s journey to discover his forgotten identity. Although this isn’t an all-that-unusual aspect of story-telling, the espionage element makes it a singular literary experience. Over the course of the novel, I progressively felt as if I were spending time with a really awesome friend. And this is owed to, I think, the “slow burn” of empathy compelled…

Book cover of The Terminal List

Carl Michaelsen Author Of The Last of a Dying Breed

From my list on to bring on an airplane/vacation.

Why am I passionate about this?

If you’re at all like me, then finding time to sit down and read a book is incredibly challenging given how busy our everyday lives are. It seems like the only time I truly can dive into a book is on vacation. And so, all of the books I recommended I have either read on vacation or on an airplane. In my opinion, a good vacation book needs to be two things. It needs to be a quick read and it needs to be impossible to put down. When I sit down to write a book, I try to keep both of these in mind!

The ultimate thrill ride from start to finish, Jack Carr’s first novel following Navy Seal Commander James Reece is one to remember. I bought this book at the airport in Anaheim, California, and started reading while waiting for my flight. A few delays and a five-hour flight later I had finished the entire book. It is a fantastically written book, laced with complex characters, government, and corporate conspiracies, and reminds us all why you must always be wary of those closest to us.

From my list on thrillers that kick terrorist butt.

Why am I passionate about this?

I have a fierce passion for justice. Studying political science in college, I keyed on moments in history where greed, power, and oppression marred human society. As a thriller writer myself (15 published titles and counting), I enjoy authors that understand the characters, settings, and combat sequences in their novels either through personal experience, training, or deep research. I work hard to ensure as wild as my characters’ adventures are, every detail is plausible. The books on this list are filled with raucous action and death-defying scenes while remaining possible.

Seth Sjostrom Why did Seth love this book?

When asked about my favorite author and influences, Vince Flynn is right at the top. 

Flynn and his character Mitch Rapp aren’t afraid to take on anyone in order to wreak justice, even if the trail leads them to the oval office itself. This is what I love about the book, series, and character, that urgent, calculated versus reckless pursuit of justice.

Act of Treason, like the rest of the Mitch Rapp series, is fast-paced, irreverent at times, and hard-hitting as CIA Agent Rapp faces down anyone, foreign or domestic, to complete his mission. I enjoy Flynn’s writing style and the emotional twists he makes Rapp and the readers endure.

Seth Sjostrom Why did Seth love this book?

When I select a thriller, I like to find someone who has developed a deep knowledge of the subject and settings either through experience or deep research. Brad Thor is an expert on terrorism and global politics.

His character, former Navy SEAL Scot Harvath, is brash and brutal as he operates to counter-terrorism in his role as a covert Homeland Security Officer. In The Last Patriot, he chases a militant Islamic cell that is protecting a lost revelation of the Prophet Mohammed that could change derail terror forever.

I enjoy reading Brad Thor books for the intensive research and logic he weaves into his stories. Reading The Last Patriot, and other titles in the series is like having a conversation over a pair of fingers of whiskey talking global politics with my friends.
