Book cover of Red Queen

Bruce Borgos Author Of The Bitter Past

From my list on a protagonist who has extraordinary capabilities.

Why am I passionate about this?

I’ve always loved peculiar heroes and heroines. Characters with strange gifts and an equal number of challenges. It started with Sherlock Holmes, whose mind fascinated me. As a child, I gravitated to the unnatural protagonist, Tarzan, in the Edgar Rice Burroughs novels and Bilbo Baggins in The Lord of the Rings trilogy. I was never a big fan of Superman, I preferred people who adapted quickly to new surroundings and could think on their feet. Once I began my writing career, I kept those protagonists in my mind. Four novels in, I do my best to capture their spirit and determination to overcome whatever lands in front of them.

Bruce Borgos Why Bruce loves this book

I loved this book because Antonia Scott might just be my favorite protagonist of all time.

She’s literally the most intelligent person in the world, with an I.Q. of over 200. She’s plagued by guilt and awkward social skills, but she has more crime-solving abilities than an entire police force. She’s Sherlock Holmes on steroids, with a hyper-intelligent sense of humor!

Book cover of A Study in Scarlet Women

Ava January Author Of The Mayfair Dagger

From my list on unconventional heroines in historical mysteries.

Why am I passionate about this?

I’ve always been drawn to stories where women defy expectations and carve out power in a world that seeks to silence them. As a writer of historical mysteries, I love exploring unconventional heroines—women who take risks, uncover secrets, and refuse to conform. The best mysteries blend atmosphere, intelligence, and a touch of rebellion, and I seek out books that do just that. Whether it’s a detective disguising her true identity or a woman outwitting society’s constraints, these stories inspire me. My book was born from this passion, and I hope readers who love fiercely independent heroines and richly layered mysteries will enjoy this list as much as I do.

Ava's book list on unconventional heroines in historical mysteries

Ava January Why Ava loves this book

Charlotte Holmes is everything I adore in a protagonist—unapologetically brilliant, unconventional, and always one step ahead. I couldn’t put this book down because it reimagined Sherlock Holmes in a way that felt fresh and exciting while keeping all the intellect and intrigue I crave in a mystery.

I loved watching Charlotte dismantle society’s expectations while outwitting everyone around her. If you love fiercely independent women and clever mysteries, this series is addictive.

Book cover of The Mirror Crack'd from Side to Side

Monique Gliozzi Author Of Facets of the Past: No Dark Deed Goes Unpunished

From my list on combining the paranormal and psychopathy.

Why am I passionate about this?

Let me tell you a little about myself. I was born in Dublin, and being the daughter of a diplomat afforded me to experience different cultures. Since childhood my fascination with the unknown caused me to gravitate towards stories related to hauntings. I shared this interest with my maternal grandparents, who contributed to my education by telling me ghost stories (some true whilst others are fictional). Tales of haunted castles were my favorite, which is reflected in my book. In later life, my own experiences with the paranormal cemented the notion of the unexplained and the thin veil between us and those departed.

Monique's book list on combining the paranormal and psychopathy

Monique Gliozzi Why Monique loves this book

What I loved about this book (which was also adapted into a film starring Elisabeth Taylor) was my first exposure to a female murderer. I liked the backstory of what motivated this woman to kill a seemingly innocent person at a party. Being a psychiatrist myself, my fascination with women who kill has inspired me to create a fictional serial killer in some of my own works.

Furthermore, the importance of a woman’s innate desire to become a mother when robbed of such happiness added to my interest in women’s psychopathology on how horrific memories of the past leave an imprint that can haunt us forever.

Book cover of I Only Read Murder

Kate Hilton Author Of Bury the Lead

From my list on amateur detective novels that keep you laughing while they keep you guessing.

Why am I passionate about this?

I’ve loved murder mysteries since childhood, and during the pandemic–when reading became a challenge–I returned to my first literary love, binging on one mystery series after another. Eventually, I decided to write one with my friend Elizabeth Renzetti. It’s been the most enjoyable writing experience either of us has had. I’ve written three other published novels, and I have a day job as a therapist (I like to think this helps with realistic characterization, but it also pays the bills). I write humor because I like to have fun at work, and I appreciate a good laugh when I’m reading.

I couldn’t help but root for Miranda Abbott, the hilariously self-absorbed heroine of I Only Read Murder. The formerly famous television star of the Pastor Fran crime-fighting series, Miranda’s path to redemption requires her to solve a real-life murder where all the suspects are members of an amateur theatrical society. I Only Read Murder is ridiculously entertaining, a very fun romp that takes full advantage of the cozy mystery tropes we all love.

Book cover of The Likeness

Abby Bardi Author Of The Book of Fred

From my list on weird groups of people.

Why am I passionate about this?

While I love many novels about individuals, there’s something about weird groups of people—for example, cults—that I’ve always been drawn to. The Book of Fred plays with this dynamic by showing the intersection between a doomsday cult, the Fredians, and the quirky liberal community that foster child Mary Fred Anderson finds herself in. What I find fascinating about cults is how appealing they are, how being part of a group has a seductive quality that can so easily go horribly wrong. I love novels and memoirs that show that seductive side while zeroing in on the complications groups pose to individual identity.

Abby Bardi Why Abby loves this book

I love all of Tana French’s taut, riveting detective novels, but this book is my favorite.

When Cassie Maddox goes undercover to investigate a murder, she finds herself enmeshed with the dead girl’s quirky group of housemates. As she’s drawn into their lives, she is increasingly emotionally involved with them in ways that charge the atmosphere with exquisite tension and regret.

I loved the way this novel drew me into the exuberant household so that, like Cassie, I fell in love with everyone, wishing fervently for things to turn out okay and knowing there was no way they could.

Book cover of A Stroke of Malice

J L Wilson Author Of Heir

From my list on mystery with first person narration.

Why am I passionate about this?

I've read mystery books since I was a kid in a small Iowa town and my mother was on the library board and in charge of reviewing books for purchase. She would bring home mysteries and I grew up reading about James Bond, The Saint, Miss Marple, and many, many other 'classic' detectives. I wrote my first mystery 'novel' when I was ten and it took me forty more years to finally decide to get serious about it. I found I wanted to write about an older demographic—my heroes and heroines are usually in their 40s or 50s. I try to make my characters believable and down-to-earth—except they get involved in the occasional murder!

J's book list on mystery with first person narration

J L Wilson Why J loves this book

I enjoy reading historical fiction, especially when I'm in the middle of writing my next mystery story. I like to read outside my genre so historical mysteries satisfy that desire for me to learn about the past while still studying how other mystery authors craft their stories.

This book features a heroine who is an artist and who was also initially ostracized by society because of her first husband. Her current husband is an 'investigative agent' in the 19th century and she's frequently drawn into his cases.

I like her because she's not afraid to speak her mind but she also knows when to keep quiet – a talent she had to acquire when dealing with some of the high-and-mighty people she meets.

Book cover of Tombland

Terry Morgan Author Of Whistleblower

From my list on international crime exotic locations nasty politics.

Why am I passionate about this?

What I look for in a book is something that triggers my serious side. So be it if that removes a whole range of fantasy books or those that merely titillate. Because I’ve traveled a lot, ‘feasible fiction’ is what I write and what I look for in other books. A story might be entirely fictitious, but as long as it’s not far-fetched, has a cast of realistic characters, an international or historic location, and keeps me on my toes to the very end, that’s great. If it’s got some politics and science thrown in, that’s even better. I hope my list lives up to expectations.

C. J. Sansom, a historian, died just recently, but he’s left a legacy of historical crime novels based around the time of Henry VIII. The main character is a charismatic, hunchbacked lawyer called Matthew Shardlake.

If, like me, you like books with strong characters, then, together with Sansom’s skill at weaving in the sights, sounds, smells, political shenanigans, and countless characters of Tudor England, Tombland is a fantastic read. It’s a long book (800 pages), so take your time on it, but I think this is historical crime fiction at its best.

From my list on virtual odyssey in ancient and modern Greece.

Why am I passionate about this?

I wrote my first thriller at age 8 about a girl who ran away and joined the circus. For later works, I, a pediatric physician, did opt to follow my English teachers’ guidance to write about what you know, including science, medicine, psychology, journalism, and my twin home countries of America and Greece. As YS Pascal, I wrote the Zygan Emprise Trilogy, which blended ancient Greek history, mythology, and literature. As Linda Reid, I co-authored the award-winning Sammy Greene thriller series with Dr. Deborah Shlian and was eager to fly investigative reporter Sammy and her ex-cop friend Gus Pappajohn to the shores of modern Athens to solve an ancient and modern mystery.

I am a British crime writer with a love of American crime fiction, particularly books with dark plots and quirky, unique characters. I am the author of the Sunday Times bestselling, multiple award-winning, Washington Poe series and the new Ben Koenig series but am first a reader—I read over a hundred books a year. I love discovering a new-to-me series that has a back catalogue for me to work through, and I appreciate recommendations. I’ve been a full-time author since 2015 and, as I suspected, it’s my dream job.

Stephen King introduced the innocent, unfiltered but extremely observant Holly Gibney in the phenomenal Mr. Mercedes.

King himself says, “...she more or less stole the book, and she stole my heart.” I completely agree, so much so she was a massive influence on Tilly Bradshaw, the super-sheltered, super-intelligent nerdy sidekick from my own Washington Poe series. She’s the first of three sidekicks in this list who will go on to get a book of their own.

Holly is out September 2023 and it’s the book I’m most looking forward to this year.
