Book cover of Short Range

Wolfric Styler Author Of Troubled Zen

From my list on action series with characters in the military.

Why am I passionate about this?

I have been in various militaries for over 17 years and am proud of my service. Troubled Zen is my first foray into the publishing world and I’m proud of what I’ve achieved. I enjoy the ex-military hero-style action/ thriller novels because I find that I can understand their mindset and relate well with their characters. I found most were male, ex-special forces so I chose a female Explosive Ordnance Disposal member as I believe that there are plenty of aspects to investigate that can show how a woman can be equally tough, stubborn, ingenious, brave, and determined.

Wolfric's book list on action series with characters in the military

Wolfric Styler Why did Wolfric love this book?

My preference is for authors to develop a series for their characters in order for me to fully embrace the depth of the character, if the character is worth developing. I enjoy picking up a novel in which I am familiar with the character as it makes it easier for me to relate to them.

The Spider Shepherd series is essential reading for me, and in particular this book. A book or two previously showed that Shepherd had finally healed enough, from his wife’s death, to find a new relationship. As a non-rule breaker, Shepherd shows that he will do what it takes to protect his family. The ending truly shocked me, leaving me chomping at the bit for the next one.

Book cover of Hello, Transcriber

Danielle Girard Author Of Up Close

From my list on thrillers set in small towns with big secrets.

Why am I passionate about this?

My first books were set in and around San Francisco, an area I knew well and with plenty of opportunities for crime stories. When we moved to Montana twenty years ago, people asked when I’d write one there. I resisted setting dark stories in my own city, where my kids were growing up. Reading about the Bakken Oil Formation in North Dakota, a boom of wealth and expansion and a subsequent bust, offered a perfect storm—the kind that drives desperation, where locals conflict with newcomers, where money—new and old—drives people to make bad decisions. After a visit to the area, the fictional town of Hagen, North Dakota, and the Badlands Thriller Series was born.

Danielle Girard Why did Danielle love this book?

In Black Harbor, Wisconsin’s most crime-ridden city, Morrissey has created a town that is a villain all on its own. A place no one wants to live. Hazel Greenlee has no choice.

An aspiring writer, Hazel is trapped in a less-than-perfect marriage and takes the only job she can find—as a police transcriber. But when her neighbor confesses to hiding the body of an overdose victim in a dumpster, Hazel sees the potential for a story that might help her break out of the frozen hell of Black Harbor.

Morrissey builds Hazel’s desperation, and the desperation of the town itself, with mounting tension so well drawn you can actually feel it in your bones and an ending so intense it leaves you breathless.

Book cover of Forbidden City

Alysa Wishingrad Author Of The Verdigris Pawn

From my list on for chess lovers.

Why am I passionate about this?

I love games; board games, card games, head games*; any kind of situation in which employing strategy is the only way forward. And yet, I’m not a big game player—aside from word games. I’m also endlessly fascinated by the mechanisms of power and how societies arrange themselves. The marriage between writing and understanding politics (in the traditional, not the partisan sense) is my true north. Writing a book in which a chess-like game provides the foundation felt inevitable for me, for what game better explores the dynamics of power and strategy? *I don’t play head games, but I do find manipulation fascinating fodder for writing.

Alysa's book list on for chess lovers

Alysa Wishingrad Why did Alysa love this book?

Let me begin by saying that if you haven’t yet read the first two books in the City Spies series, please get on it. Packed with adventure, fantastic characters, and brilliant plots twists, the entire series is a complete treat. As with the two previous installments, the book follows a diverse group of international kids who’ve been brought together to keep the world safe from the nefarious Umbra, a secret organization bent on world domination. The plot of this adventure revolves around team member, Paris, when he’s sent undercover to an international chess tournament to keep tabs on the son of a North Korean nuclear physicist. Like a well-played game of chess, the story relies on clever tactics, keen insights into your opponent, and good old-fashioned strategy.

Book cover of Hidden

Jan Sikes Author Of Jagged Feathers

From my list on unique and compelling character-driven stories.

Why am I passionate about this?

I have been an avid reader since I could first decipher words. But I am also an author. I write compelling stories from the heart and love character-driven stories. Therefore, I gravitate toward reading stories that tick these boxes for me. I have read thousands of books in my lifetime, and still feel the same excitement when I open a new one that I felt when I first read the Dick and Jane primers and Grimm’s Brothers Fairy Tales.  

Jan's book list on unique and compelling character-driven stories

Jan Sikes Why did Jan love this book?

This book appealed to me on several different levels. First, I’m a sucker for a deep dark secret and the story begins with the indication that the character is hiding something huge. Secondly, it is a steamy romance with love scenes so hot the pages sizzle. Thirdly, the plot is so intricately woven that I couldn’t stop reading. The story takes the reader inside a religious cult and exposes practices that are shocking and frightening. I learned what makes people fall for the artful deception of the leader, and the dangers of escaping. I rooted for the characters all through the book, although at times, I wanted to shake both of them and get them to be honest with each other. If you love a sizzling romance with tons of suspenseful action, you’ll devour this well-written story!

Book cover of Under and Alone: The True Story of the Undercover Agent Who Infiltrated America's Most Violent Outlaw Motorcycle Gang

Gary Taylor Author Of Luggage by Kroger: A True Crime Memoir

From my list on true crime memoirs written by actual participants in the story.

Why am I passionate about this?

During my 45-year career as a newspaper and magazine journalist, I covered a wide range of events on a daily basis. As a police and courts reporter for two daily newspapers, I spent many hours researching and writing about crime and legal affairs. As a reader, I’ve enjoyed true crime. As the target of a true-crime myself in 1980, however, I became more fascinated with the sub-genre of the true-crime memoir in which a participant in a true-crime shares insider details of the story without seeking pity or glorification from the reader through objectivity and self-deprecating humor. It’s a fine line. When an author manages to walk it, however, the result proves inspirational.

Gary Taylor Why did Gary love this book?

Vietnam vet William Queen was capping a 20-year law enforcement career in 1998 when the ATF agent wangled an invitation to join the San Fernando Valley chapter of the notorious Mongols motorcycle club under the code name Billy St. John. He spent the next 28 months rising undercover to the rank of treasurer and vice president, allowing him to provide documents for the arrest and indictment of 54 members by 700 officers in four different states. Queen’s 2005 bestselling true crime memoir of his Mongols days ranges from bone-chilling to side-splitting for terror and laughs. Although Mel Gibson reportedly bought the screen rights, a movie has yet to appear.

When veteran law-enforcement officer and lifelong motorcycle lover William Queen penetrated the San Fernando chapter of the notorious Mongols, he was at the mercy of psychopaths who sought to have him prove his fealty by any means necessary, from selling and doing drugs to arms trafficking, driving getaway cars and, in one shocking instance, stitching up the face of a Mongol 'ol' lady' after a brutal beating at the hands of her boyfriend.

Yet despite the constant criminality of the gang, Queen came to see the genuine camaraderie they shared. When his lengthy undercover work totally isolated Queen from his…


Book cover of An Ember in the Ashes

Christina Bacilieri Author Of The Last Refuge

From my list on YA books that blend fantastical magic with dystopian worlds.

Why am I passionate about this?

I’ve always been drawn to stories where characters discover the magic within and channel it to confront overwhelming odds. Dystopian fantasies meld the intricate worldbuilding of an oppressive world with a character’s unique abilities to fight back. When I was a young adult, these types of books made the most challenging moments in life manageable, not only for the escapism but for their message of hope. They reminded me I wasn’t alone and that my voice mattered. At their core, they’re made for the dreamer in all of us. They inspired me to become an author and write about the transformative power of self-discovery.

Christina's book list on YA books that blend fantastical magic with dystopian worlds

Christina Bacilieri Why did Christina love this book?

Laia and Elias stole my heart, while the Commandant’s cruelty stole my breath. Sabaa Tahir’s ability to evoke such powerful emotion with this story set in reimagined Ancient Rome was nothing less than masterful.

The characters are faced with impossible choices, which kept me asking questions about what I would do in their situation. I thought the integration of elemental magic was woven in perfectly. I’m a sucker for it and could lose hours thinking about what abilities I’d wish for.

Laia is spying on the Martial Empire for the rebels in exchange for their help rescuing her brother when her path collides with Elias, an enforcer of the tyrannical regime. Both dream of freedom, and we root for them to find it together in this ruthless world.

Book cover of Hot Season

Aimee Hoben Author Of The Third Way

From my list on activism to inspire and mobilize.

Why am I passionate about this?

I began as an activist in high school, knocking on doors to enlist support for clean water and air, and more recently, for my favorite candidates for local, state, and federal office. Some of my most meaningful work was as a lawyer and volunteer on land conservation deals for an agricultural land trust. Fiction has an amazing power to recharge us and to shift our perspectives to imagine the world differently. My favorite books are always ones that teach me something interesting. My recent activism has been motivated by my frustration with our political process, including the 2010 Supreme Court case of Citizens United declaring corporations to be “persons” under the law.

This story about three restless college students at a liberal arts enclave in the southwestern desert who become embroiled in a protest to stop a pipeline reminded me of my days as a malcontent at the University of Colorado Boulder. When the FBI comes to town in pursuit of an alum wanted for “politically motivated crimes of property,” rumor has it that undercover agents are enrolled in classes, making the college dating scene that much stranger. The characters variously discover a passion for activism, the seduction of the unknown, and their own voices. This book is fun, interesting, and evocative.

Ursula Wong Why did Ursula love this book?

An American Spy shows us the people-side of the spy trade. A masterful Chinese agent has avenged his son’s death by massacring almost everyone in the secret black operations organization called the Department of Tourism (DOT). A CIA supersleuth and brains behind the DOT aims for revenge with the help of reluctant hero, Milo Weaver.

Aside from a beautifully complex story, I love Mr. Steinhauer’s spies. After marrying his daughter-in-law, the Chinese agent makes stunning observations about the intrigues of the communist intelligence apparatus. Poor Milo is constantly distracted by a physical injury and a crumbling home life. His agent friends use drugs to cope. Even the beautiful and highly effective Leticia Jones is more about dealing with stress than doing nasty things.

The story made my head spin, but isn’t spying like that?

From my list on how people become spies.

Why am I passionate about this?

Looking at photographs after my father died, when still living in Spain, I reflected on what life had been like for young men of the WWII generation. This sparked the start of my Peter Cotton series. Living abroad for so long, having more than one language and culture, gives people dual perspective, a shifting identity, which is something that fascinates me—and makes Cotton ideal prey for recruiting as an intelligence agent. I also wanted to explore the complex factors in the shifting allegiances after WW2, when your allies were often your worst enemy. All these are themes that recur in the books chosen here.

Aly Monroe Why did Aly love this book?

BOX 88 is a thoroughly modern-day spy story set in two timeframes. Lachlan (‘Lockie’) Kite, the protagonist, is poles apart from Lawton’s Joe Wilderness. An apparently chance meeting at the funeral of an old school friend leads him to be abducted. Flashback 30 years, and we see how he was recruited to a secret cell of intelligence operatives (Box 88) when barely out of his upper-class boarding school. He is trained and asked to undergo a mission while spending the summer at the house of a school friend in France. While there, he falls heavily in love, and somehow manages to carry out his mission—albeit with devastating consequences. This portrayal of an intelligent young man growing up feels real and is beautifully handled. The start of a great series.

Book cover of Flamingo Road: A Mystery

Virginia Slachman Author Of Blood in the Bluegrass

From my list on a courageous main character who wins.

Why am I passionate about this?

I’m an undying, relentless, optimistic champion of right winning over wrong, of justice prevailing over injustice, and of good people and animals (especially horses) being protected, championed, and loved. And I know from experience that all of this is seldom easy when the stakes are high. Couple that with my love of horses, especially Thoroughbreds, and you might understand that I admire main characters who are committed to protecting the innocent and bringing the bad guys to justice, whether that’s in the human or the equine world. And I love learning almost as much as I love people with character, heart, and courage. These books, I think, check all these boxes.

Virginia's book list on a courageous main character who wins

Virginia Slachman Why did Virginia love this book?

By now, you probably think I only read books by male authors who create male protagonists. Nope! Here’s a case in point. Sasscer Hill is a woman after my own heart—she writes horse racing mysteries set in the Thoroughbred racing world (!), just like me. Unlike me, Sasscer Hill was a racehorse breeder, trainer, and rider—and she brings all that experience to bear on creating an incredibly realistic setting for all her racing novels. I know a lot about Thoroughbred racing myself, so one thing I’m really drawn to in her books is how authentic they are. She does the “behind the scenes” thing with pinpoint accuracy and ease. And I love that she doesn’t shy away from the “dark underbelly” of racing, either.

In this book, her main character, Fia McKee, is on leave because she uses a little too much force when making an arrest. Ok, yeah, I…
