Book cover of Blood Work

Stephen B. King Author Of Forever Night

From my list on catching a serial killer and how they became monsters.

Why am I passionate about this?

Like most people I know, I have always been fascinated with serial killers, and more importantly why they do what they do. What makes one man murder multiple victims while another with a similar upbringing sells white goods and wouldn’t attract a traffic ticket. In my books, I am as interested in showing my readers why a killer kills, as I am in the hunt to catch him. My goal is to not so much get the reader to ‘like’ the antagonist but to understand, and dare I say even feel sorry for him. We are all products of our environment and upbringing, yet some of us murder others for fun.

Stephen B. King Why did Stephen love this book?

Retired FBI profiler Terry McCaleb is recovering from a heart transplant he required after a heart attack he suffered while hunting a serial killer. When a woman urges him to help investigate the murder of her sister who was shot dead during a robbery, Terry discovers it is her heart he received. Possibly the killer wanted McCaleb to recover so he could resume his pursuit. This is one of the finest stories I have ever read; deeply moving, and a very exciting read.

Book cover of Mortal Prey

Gary J. Rose Author Of The Fourth Reich

From my list on protagonists that helps the reader solve the crime.

Why am I passionate about this?

As a retired police officer, I believe that my insight into police procedures helps move my novels along. By creating a strong female protagonist, FBI Agent Jeannie Loomis, my readers get the best of both worlds. A somewhat flawed female main character who is still a dedicated law enforcement officer who believes, similarly to Lucas Davenport of the Prey Novel series, and Jack Reacher of the Reacher novels, that the ends, justify the means.

Gary J. Rose Why did Gary love this book?

Great follow-up novel in Sanford’s Prey Series concerning a serial female killer. Sanford leaves the reader from a previous prey novel, where the female serial killer escapes.  This leaves his readers with a desire to learn more….a continuing storyline…and he more than satisfies that with her return in Mortal Prey.

Book cover of The Midnight Show

Yakira Goldsberry Author Of Curse of the Midnight King

From my list on YA retellings of The Twelve Dancing Princesses.

Why am I passionate about this?

I’ve been in love with fairytales since childhood when I picked up a collection of fairytales by Hans Christian Anderson. These stories shaped my imagination, so much so that I longed for distant mysterious lands full of magic, wonder, and mystical creatures. Though in a way, I guess I did live a bit of a fairytale, having grown up surrounded by thick woods and open fields, as one of twelve siblings. Now as an adult, I still wish I could escape to distant fantastical lands, but I’ll just have to stick with the ones I find between the pages of books and the ones in my own head!

Set in a fantastical world based on the roaring 20s, Pennington’s take on the tale is very unique! Bastion and Dayo quickly became some of my favorite characters, and I loved all of the intrigue and mystery that surrounded them both. Not to mention the subtle African influences on the world!

Book cover of House on Fire

Kayla Perrin Author Of We'll Never Tell

From my list on surprise suspense twists.

Why am I passionate about this?

I’m absolutely passionate about suspense stories, especially ones with killer twists. Maybe it’s all the crime shows I watch, but the motives for crimes are so wide and varied, and I love when the unexpected is explored in fiction. I’m also intrigued by stories about missing people and the myriad of reasons behind why they go missing–especially when things aren’t always what they seem. Whether it’s the missing who return years later or hints of them suddenly appear, I can’t help but get wrapped up in a story that keeps you on the edge of your seat guessing what might happen next! I try for great twists in my novels.

Kayla Perrin Why did Kayla love this book?

All of the authors I love do twists really well, twists that make sense and blow you away–no matter how much you try to guess them. This story is set in the world of addictive pharmaceuticals and the desire to make a corrupt company that’s hiding secrets pay for the deaths of innocent patients. A whistleblower is killed early in this story, and this sets everything off. It’s fast-paced with so much action, including bullets flying in the Caribbean as the main characters risk their lives to get incriminating evidence. The ending…oooh, it doesn’t get better than a Joseph Finder twist!

Book cover of The Suicide Murders

Rosemary McCracken Author Of Uncharted Waters

From my list on Canadian mysteries.

Why am I passionate about this?

I’m a Canadian writer who started writing fiction after a career as a journalist at newspapers across the country. I’ve always marvelled at the diversity of Canada, and I try to portray that diversity in my own stories set in Toronto, one of the world’s most multicultural cities. And I revel in stories by fellow Canadian crime writers, tales filled with First Nations characters, and characters with Ukrainian, Russian, Asian, African, and British backgrounds, stories set in various parts of our far-flung country. The five novels I have focused on here are just a few of my favorites.

Rosemary's book list on Canadian mysteries

Rosemary McCracken Why did Rosemary love this book?

The Suicide Murders introduces Benny Cooperman, one of the most beloved characters in Canadian fiction, and a major influence on my own crime fiction. Howard Engel’s 14 Cooperman novels are filled with sharp dialogue and sparkling wit, and play with the tropes of detective fiction. A nice Jewish boy who runs a small detective agency, Benny doesn’t swear or carry a gun, and he’s squeamish about violence—much like my Pat Tierney protagonist--giving the PI genre a distinctly Canadian twist. 

The Suicide Murders was released in 1980, and Engel’s impact on crime fiction was enormous. He set most of the Cooperman books in the fictional town of Grantham, recognizable as St. Catharines, Ontario, where he grew up. Engel proved that writers could set stories on their own turf and have them published.

Ontario PI Benny Cooperman is on the case of a suspicious suicide in this “convincingly complex” mystery “with an ironic sense of humor” (Kirkus Reviews, starred review).

Myrna Yates shows up at Benny Cooperman’s office asking him to check up on her husband, the contractor Chester Yates, who she believes is having an affair. It seems like an open-and-shut case, until Cooperman finds out that the straying spouse has committed suicide. Something doesn’t add up; Mr. Yates bought a 10-speed bicycle just 2 hours before he killed himself. Could this “suicide” in fact be murder? The Jewish detective’s got a…

Rod's 3 favorite reads in 2023

Rod Kackley Why did Rod love this book?

It's 1932. For the best history thriller I have ever read, Max Allan Collins spins together characters like Al Capone, Frank Nitti, George Raft, and even Ronald "Dutch" Reagan.

True Detective is the story of a young cop, Nathan Heller, who vows never to be corrupted, even though he's already done something and will do more on the wrong side of the law. Maybe.

While it's a fantastic story, and the characters and dialogue are unbeatable, the best part for me is that while this didn't happen precisely as Collins wrote it, the story was pretty damn close to reality.

What is this book about?

In the mob-choked Chicago of 1932, private detective Nathan Heller may be willing to risk his life to earn a Depression dollar, but he never sacrifices his sardonic wit. Now, author Max Allan Collins (Road to Perdition) reissues the contemporary classic that introduces the wise-cracking Nathan Heller in all his guts and glory.

When Mayor Cermak's "Hoodlum Squad" brings Heller along on a raid with no instructions but to keep his mouth shut and his gun handy, he becomes an unwitting, unwilling part of a hit on Al Capone's successor, Frank Nitti. As a result, Heller quits the force to…

Mark Love Author Of Why 319?

From my list on contemporary mysteries.

Why am I passionate about this?

I’m a contemporary mystery junkie. Realistic tales, set in the modern world always grab my attention. In a creative writing course in college, one professor suggested the old ‘write what you know’ approach. I don’t know everything, but I know what I like. Mysteries! I thrive on distinctive characters, those who are willing to put every effort into getting to the bottom of the situation. Sharp, tight dialogue and descriptions are essential. Give me that, and I’ll be back for more. This is my passion. Come along if you want a thrill and a surprise or two.

When it comes to private detectives, Elvis Cole is my favorite. He’s got the combination of wit, intelligence, and experience that others strive for but often fall short. Pair him with Joe Pike and you’ve got an unbeatable combination.  

I really enjoy how Pike is more inclined to let his actions do the talking, while Cole is the voice telling the tale. This latest book includes the return of Lucy, Cole’s longtime lady friend, who helps smooth out his rough edges.

Crais paints a great landscape, where Elvis and Joe run through the Los Angeles area. This is a great example of how what looks like a simple case can easily be far more complicated.

John J. Jessop Author Of The Realtor's Curse

From my list on detectives from wacky to dark and deadly.

Why am I passionate about this?

With a Ph.D. in pharmacology, I worked in drug development for many years. Now a published author, mysteries are my passion. I love to laugh and enjoy the humor of Steve Martin and Mel Brooks, so I’ve written a medical comedy mystery series. This dysfunctional detective series, starting with Pleasuria: Take as Directed, takes place in the pharmaceutical industry, a surprisingly fertile ground for humor, and murder. I’ve also written a dark mystery series, The Guardian Angel series. This includes a serial killer, a cult leader, and a touch of vigilante justice. With my overactive imagination you’ll enjoy engaging characters and unique plots.

Robert B. Parker’s Cold Service is one of my favorite Spenser novels because it provides more insight into the character Hawk. Hawk is in the hospital, three bullets in his back from trying to protect a bookie from the Ukrainian mob. The Ukrainians are spreading their turf from NYC to the Boston area (a town called Marshport). Spenser comes to the rescue, and the two men take on the impossible task of defeating the Ukrainian mob and their Afghani heroine-dealing overlords while avenging Hawks shooting. Alone, Hawk can’t deal with the thought of showing weakness and Spencer ponders his mortality. Together Spenser and Hawk appear to be invincible. Their code allows them to engage in brutality and come out as likable characters. The way in which Parker spins a tale using simple dialogue is ingenious. His main characters Spenser, Hawk, and Susan Silverman are a joy to get to know…

Nathan's 3 favorite reads in 2023

Nathan Abrams Why did Nathan love this book?

I love this author’s adult work, especially his Atticus Pünd mysteries, in which he inserts a book within a book. The Twist of a Knife is a good old-fashioned crime/detective mystery in which the main character is a semi-fictionalized version of the author who teams up with an enigmatic detective to solve crimes in London.

Not only are many of the settings familiar to me, but Horowitz also loves wordplay and puns, and often anagrams provide clues to unravel the mystery.

It is the fourth in a series and I am excited to learn that a new one is on the way shortly.

From my list on Native romance by Native authors.

Why am I passionate about this?

I am an award-winning author of sex-positive contemporary romance and a citizen of the Cherokee Nation. As a reader, I’ve grown weary of Native American romance characters who are mostly caricatures and stereotypes. Last year, I went on a quest to find romance stories that portrayed contemporary Native characters experiencing love as they navigated real life in the 21st century. And who better to tell those stories than Native authors using their own voice? Now that I’ve found several great Native romance authors, I want to share these recommendations far and wide. Come, come, read Native romance!

I don’t usually read billionaire romance because the billionaires are often crappy humans, and I don’t enjoy reading about crappy people getting a happily-ever-after. This book was a great exception. Adam Redhawk isn’t just a billionaire, he’s an Eastern Band Cherokee billionaire who was taken from his home and community when he was a child. Now he’s hired a PI to help him find his long-lost siblings to reconnect with the past that was stolen from him. I enjoyed the romance and the characters a lot. If you read billionaire romance, let this be one of them.
