Book cover of Killing Floor

Patrick Weill Author Of The Mazatlan Showdown

From my list on action thrillers to keep you awake past bedtime.

Why am I passionate about this?

I remember carrying home tall stacks of library books in the summertime and spending entire days immersed in my heroes’ latest adventures as a kid. This continued as I grew up, as I learned that I ought to be a hero, too, by confronting evil both within and without. So I took steps to face my fears, and now when I write about good guys fighting bad guys in my own action fiction, it’s with a real passion for doing what’s right, for making this world better, even if it’s in my own way and only just a little. 

Patrick's book list on action thrillers to keep you awake past bedtime

Patrick Weill Why Patrick loves this book

As I indicated earlier, I am a Lee Child superfan. I’ve read all his original books. A thick (and expensive) biography. A long essay he wrote on heroism. All his short stories. You get the idea. So it was fun to re-read this book, his first.

It wasn’t what I remembered, that’s for sure! Yes, the action scenes are vivid and instructive (Child writes about the utility of a headbutt versus the risk of breaking your hand with a punch), and the action is what I remember most. But there’s more to this book than fights: there’s a major romance, which the author writes with gusto and in detail, heavy on feelings, not on private parts; the prose is better than solid, with imagery that really makes it come alive; and the story is plausible and tightly woven, with plenty of surprises.

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

Jeff Kerr Author Of Blunt Force Trauma

From my list on crime fiction that sucked me into a series.

Why am I passionate about this?

When I was a boy, my father filled our house with books. From an early age, I immersed myself in whatever he was reading, especially spy thrillers (John LeCarre was his favorite) and crime fiction (the first I recall reading was Joseph Wambaugh’s The Onion Field). I loved those books. What captivated me most were stories that provided clues but made me piece them together to draw my own conclusions. I strive to deliver this same experience to the readers of my novels by providing entertaining tales with unexpected, yet plausible endings.

Jeff Kerr Why Jeff loves this book

This book introduced me to the gritty world of Los Angeles police detective Harry Bosch. I love Bosch’s smarts and toughness, yet beneath his hard exterior lurks a sensitive heart. He is fond of saying, “Everybody counts, or nobody counts,” and he means it.

Whether the victim is a rich businessman or an impoverished drug addict, Bosch pursues justice with the tenacity of a bulldog. Not only that, he makes tough choices with an ironclad sense of right and wrong. After reading it, I devoured everything Michael Connelly has written. I’m that fan who pre-orders his next book as soon as the announcement hits my inbox.

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 Big Little Lies

Libby James Author Of Concessions

From my list on exploring morally gray characters and the pursuit of power.

Why am I passionate about this?

I lived vicariously through Nancy Drew when I was young. I was naturally observant and curious, and my mom was known to tail a car through our neighborhood if she thought the driver looked suspicious. So, it’s not surprising that I developed a love for all things thrilling. While working in the oil and gas industry for fifteen years, I spent some time focused on a foreign deal that served as inspiration for my first novel. I worked with people seeking power; negotiations bordered on nefarious; the workplace became toxic. If you ever ponder the moral implications behind the pursuit of power, you’ll enjoy the books on this list!

Libby's book list on exploring morally gray characters and the pursuit of power

Libby James Why Libby loves this book

There’s nothing better than a little gossip, especially when it’s about grown, mostly rich women, who enjoy knowing everything about everyone else but will do anything to protect their own secrets.

Big Little Lies lets the reader peek into the lives of a group of women and how their beliefs and actions are interwoven. Every action has a reaction, and consequences are very real, yet there is a fierce loyalty that drives the women to protect one another.

It’s not entirely clear who is “good” and who is “bad,” which makes it fun to play along and watch alliances shift or strengthen. You’re also not entirely certain what has happened, which I like because I usually always guess the ending!

I tell everyone I know that if they want a book with incredible character development, read The Girl with a Dragon Tattoo.

This book is highly atmospheric. You can feel the biting cold, the fear, the pain. It also has characters with questionable ethics. It made me question how I feel about vengeance and retribution. Some of the content is very dark, yet it doesn’t feel sensationalized.

This is also a thriller with hints of a happy ending—at least, for some people—while also leaving some things uncertain or unresolved. I prefer a thriller to leave me hanging a little . . .

Forty years ago, Harriet Vanger disappeared from a family gathering on the island owned and inhabited by the powerful Vanger clan. Her body was never found, yet her uncle is convinced it was murder - and that the killer is a member of his own tightly-knit but dysfunctional family.

He employs disgraced financial journalist Mikael Blomkvist and the tattooed, truculent computer hacker Lisbeth Salander to investigate. When the pair link Harriet's disappearance to a number of grotesque murders from forty years ago, they begin to unravel a dark and appalling family history.

But the Vangers are a secretive clan, and…


Book cover of The Gray Man

Ted Galdi Author Of Black Quiet: A Cole Maddox Action Thriller

From my list on action thrillers with rule-breaking heroes.

Why am I passionate about this?

I’ve written several action thrillers about main characters who defy the rules. In my opinion, the key to these stories is giving your protagonist a good cause to break the rules for. Readers don’t want to get behind someone who wreaks havoc just to entertain himself. However, readers can identify with someone who’s pursuing an admirable goal and will stop at nothing to achieve it. These stories shouldn’t motivate anyone to break the law in real life. They serve as a metaphor for going against convention to overcome obstacles. Hopefully, my books, and those of other authors, encourage people to take on challenges in ways they haven’t yet considered.  

Ted's book list on action thrillers with rule-breaking heroes

Ted Galdi Why Ted loves this book

In The Gray Man, a highly skilled, former CIA operative tries to rescue a colleague and his family while various teams of elite assassins try to stop him however they can.

The Gray Man – AKA Court Gentry or Sierra Six – doesn’t follow anybody’s orders, even those of the most powerful institutions on the planet. Though rebellious, he has morals and only applies his skillset for good.

My favorite part of this book were the action scenes. I liked how big they were, but also the variety of arenas, weapons, and opponents. Also, the Gray Man takes a serious beating through the chapters. Because he’s hurt, but still kicking, the fights progressively get more challenging for him, and more dramatic.

I was young when I first read The Firm and remember being intrigued by the glossy, glitzy world of high-paid lawyers. 

I was also scandalized by moral ambiguity, questionable ethics, and an imperfect ending. I fell in love with the gritty protagonist, Mitch, yet grieved some of the choices he made.

I usually know how books will end, but this one kept me guessing and left me shocked and surprised and wondering if ambition can be good or if it always leads to some kind of destruction, whether personally, professionally, or spiritually.

Book cover of Open Season

Berrick Ford Author Of Dead Water

From my list on criminally good crime writers that you may not have heard of.

Why am I passionate about this?

I read a lot of crime novels but get frustrated by the ones that don’t seem to be grounded in any reality. I get irritated when police procedural novels like any real ‘procedure’, and I find ‘maverick’ cops a tedious trope because it’s rarely done as well as the true originals like Morse. Of course, there’s a lot more freedom with PIs or ‘amateur sleuths’, but I still want the books to have some relation to reality. I’m not keen on too many coincidences either. Perhaps I’ve become hard to please!

Berrick Ford Why Berrick loves this book

The protagonist, Joe Picket, is a game warden in Wyoming. I learned so much about his job stopping poachers, and about life in rural Wyoming, but the story is also so well written with a warmth and humanity that some crime novels lack.

I loved that he was a father with two young children, not earning very much in the career he loves, with all the stresses of modern life and a difficult and often dangerous job.

There are 26 books in the series, the most recent came out in March 2026.

Why am I passionate about this?

As a doctor, writer, and mother of middle schoolers, I was ready to scintillate the sixth-graders when I volunteered for the chicken wing dissection class, demonstrating the exciting connection between muscles, tendons, and bones. I opened and closed the wing, placed it in their hands, and showed them the thin strips of tissue coordinating all the action. Did I see fascination? Excitement? Feigned interest of any sort? Sadly, no. They were much more enthusiastic about a different topic I volunteered for. Mythology. Greek gods. Beasts with multiple heads. They knew everything, and I knew books like Rick Riordan’s The Lightning Thief series were the reason. Books can entertain and educate.

Mary Martinez Why Mary loves this book

I read this book as a contest judge. I’d never heard of the author before. Little did I know that I’d fall in love with Morgan and Lance. Hooked from the first book. Morgan is caught between a rock and a hard place. Tessa, who couldn’t be more ‘girl next door’–also Morgan’s kids’ babysitter–was murdered. Her neighbor needs Morgan to defend her son, who is accused of the murder. Morgan has known him for years and is determined to prove his innocence.  

Morgan asks her friend Lance, an ex-cop turned private investigator, to help solve the murder. I loved how they formed a relationship that developed with each new book of the series. I love series, especially when I love the author. I highly recommend this book.
