Book cover of Something Wicked This Way Comes

Bryan L. Young Author Of A Children's Illustrated History of Presidential Assassination

From my list on morbidly curious kids and their adults.

Why am I passionate about this?

I’ve been a nerd for the morbid for as long as I can remember. When I was a kid, I tore through all the books on the shelves in my house, whether they were appropriate for my age group or not. I started tearing into Stephen King books at 8 or so. I remember vividly copying language out of Christine when I was about 10 on the playground and getting in a lot of trouble for it. But I turned out okay. I really do believe that kids have a fascination for things above their age range, and adults enjoy it, too, and I still love all of these.

Bryan L. Young Why Bryan loves this book

There’s something deliciously attractive about this book.

The language Bradbury uses draws me in every time I visit it, and it keeps me hooked. This was another book I found as a kid, and it left its hooks in me from when I was young.

Is it morbid? There are definitely morbid parts to it. And it deals with life-and-death situations, but it’s just so good. I never wanted it to end.

By Ray Bradbury ,

Why should I read it?

12 authors picked Something Wicked This Way Comes as one of their favorite books, and they share why you should read it.

What is this book about?

One of Ray Bradbury’s best-known and most popular novels, Something Wicked This Way Comes, now featuring a new introduction and material about its longstanding influence on culture and genre.

For those who still dream and remember, for those yet to experience the hypnotic power of its dark poetry, step inside. The show is about to begin. Cooger & Dark’s Pandemonium Shadow Show has come to Green Town, Illinois, to destroy every life touched by its strange and sinister mystery.

Book cover of Pet Sematary

S.M. Sykes Author Of Blood Stained Bricks

From my list on horror and dark fantasy about being hunted: run, scream, bleed.

Why am I passionate about this?

I’ve been a fan of horror and dark fantasy for as long as I can remember. There’s something irresistible about slipping into stories that could happen, however unlikely. The closer a tale inches toward reality, the more thrilling it becomes. As a writer in this genre, my appreciation has only deepened. I’ve learned how delicate the balance is walking that fine line between realism and fantasy, all while keeping the darkness close enough to unsettle, but not so overwhelming that it drives the reader away. These books walk that line better than any I’ve read.

S.M.'s book list on horror and dark fantasy about being hunted: run, scream, bleed

S.M. Sykes Why S.M. loves this book

This book messed with my head in all the right ways. I expected scares, but I didn’t expect the emotional gut-punch.

It’s not just about death; it’s about grief, denial, and how far someone will go to outrun the pain.

You feel the characters trying to escape what’s coming, running from fear, from loss, from truth, but it always catches up. The horror creeps in slowly, then hits like a truck, literally. Once the line between life and death is crossed, there’s no turning back. 

It’s one of the few books that left me genuinely unsettled because I understood the choices, even when they led straight into darkness.

Why should I read it?

17 authors picked Pet Sematary as one of their favorite books, and they share why you should read it.

What is this book about?

Now a major motion picture! Stephen King’s #1 New York Times bestseller is a “wild, powerful, disturbing” (The Washington Post Book World) classic about evil that exists far beyond the grave—among King’s most iconic and frightening novels.

When Dr. Louis Creed takes a new job and moves his family to the idyllic rural town of Ludlow, Maine, this new beginning seems too good to be true. Despite Ludlow’s tranquility, an undercurrent of danger exists here. Those trucks on the road outside the Creed’s beautiful old home travel by just a little too quickly, for one thing…as is evidenced by the…


Book cover of 1st to Die

Elizabeth Ducie Author Of Counterfeit!

From my list on strong women fighting crime together.

Why am I passionate about this?

I was able to read before I went to school and have never been without a book since; frequenly having several novels on the go at one time. I started with adventures and classics, moved on to fantasy and later discovered crime fiction. Having been educated at an all-girls school where we assumed we could do everything, it was a shock to enter the world of science and engineering in the 1970s and find that women were not considered as strong and powerful as men, and certainly not as good. Even though times have changed somewhat, I still love finding books (especially series) where crime solving and sisterhood go hand-in-hand.

Elizabeth's book list on strong women fighting crime together

Elizabeth Ducie Why Elizabeth loves this book

This book made me realise that women’s role in fiction didn’t have to be the ‘little woman’ or the ‘love interest’.

It was published back in 2001 when female protagonists were a rarity, but James Patterson gives us not one, but four strong women who get together to solve crimes that the police alone cannot. I love the fact that these women are willing to break the rules in order to succeed in a man’s world. But at the same time, they are a club in the traditional sense: they eat, drink, and have fun together, while watching each other’s backs.

It was a wonderfully empowering experience to discover this book (and even more so when I realised there were a whole series of books about the same group of women).

Book cover of Mallory's Oracle

Christa Loughlin Author Of The Pallbearer

From my list on mystery thrillers that keep you glued to the pages.

Why am I passionate about this?

I have always had a passion for anything crime fiction—books, movies, podcasts, or TV shows. It didn’t matter. I loved it all. It was probably because I grew up in a family with six police officers that seldom talked about anything unrelated to policing. I was like a sponge and picked up some terminology and learned about different police procedures they would discuss. There was rarely a family gathering that didn’t have some type of story or anecdote being shared by each of them and I always found myself being drawn right in. For those reasons, I fell in love with trying to figure out the who’s, how’s and why’s of any story. 

Christa's book list on mystery thrillers that keep you glued to the pages

Christa Loughlin Why Christa loves this book

Kathy Mallory is a character unlike any other. Kathy was a child of the streets who had the good fortune of being adopted into the loving home of a police officer who saw her brilliance and resourcefulness even at a young age. Years later, Kathy has become an NYPD officer who brings justice to victims through her own sense of right and wrong. She is a street-hardened, lone wolf who doesn’t stop until she gets what she wants. I love the complexity of this tough-as-nails female officer who bends all the rules in her pursuit of justice. This book is so well written I immediately read every book I could find by this author.

2 authors picked Mallory's Oracle as one of their favorite books, and they share why you should read it.

What is this book about?

Jonathan Kellerman says Mallory's Oracle is "a joy." Nelson DeMille and other advance readers have called it "truly amazing, " "a classic" with "immense appeal." It is all of that, and more: a stunning debut novel about a web of unsolved murders in New York's Gramercy Park and the singular woman who makes them her obsession.

At its center is Kathleen Mallory, an extraordinary wild child turned New York City policewoman. Adopted off the streets as a little girl by a police inspector and his wife, she is still not altogether civilized now that she is a sergeant in the…


Book cover of The Bad Place

Brett McKay Author Of The Intruders

From my list on warp your brain with shocks, twists, and horror.

Why am I passionate about this?

It wasn’t until high school when I read Stephen King’s Night Shift that illuminated the genre for me—horror. My first short story was The Dark Shadow, and it fit me like a glove. My writing is inspired by the books I like to read, as I’m sure it is with all writers, and I write characters that I know and in settings I am familiar with for authenticity. The years of experience have honed my craft, and my books are a culmination of my favorite things—supernatural horror, suspense, heart, drama, westerns, and action.

This book had me at the main character hiring a private eye to follow him because he is waking up in a different location each morning with no memory of how he got there but his pockets are filled with diamonds.

This story delved into the madness of psychos while also plummeting me into other worlds and satisfying my hunger for supernatural elements. I couldn’t love this book more.

Christa Loughlin Why Christa loves this book

This book about a sadistic serial killer hunting women near Puget Sound, Washington made me check in the closet and under the bed. It was graphic and terrifying, and I simply couldn't stop reading it. An oddly paired detective duo, the easy, natural banter makes Kendall Stark and Josh Anderson believable right from the start. I fell in love with this book the more Kendall came to life through great descriptions of her caring but humanly flawed character. The addition of Pathologist Birdy Waterman as a second strong female character left me feeling that together these women meant business. This book frightened me enough to look over my shoulder when I think I’m alone.

What is this book about?

The bodies are found in towns and cities around Puget Sound. The young women who are the victims had nothing in common-except the agony of their final moments. But somebody carefully chose them to stalk, capture, and torture...a depraved killer whose cunning is matched only by the depth of his bloodlust. But the dying has only just begun. And next victim will be the most shocking of all...

Christa's book list on mystery thrillers that keep you glued to the pages

Christa Loughlin Why Christa loves this book

I recommend this book because it is a page-turner from the very beginning with a sick plot thanks to the warped mind of its featured killer. With no time to lose, veteran homicide detectives Sam Kovack and Nikki Liska aided by the FBI race to stop a serial killer who is brutalizing women. I love the strong relationships between partners, Kovack and Liska but also the level of tension between Kate Conlan and FBI Profiler, John Quinn. The characters are well-written and come to life before your eyes. I am personally drawn to the strength of the female crime fighters in this book. The gruesome crimes are thankfully overshadowed by the developed and relatable characters.

R.'s book list on staying awake at night

R. David Fulcher Why R. loves this book

Phantoms is an exceptional book. When two sisters discover that their hometown of Snowfield, CA is deserted, the reader is instantly pulled into the mystery. Koontz’s powerful description of finding homes deserted without warning, with dinner still on the table in some cases, is uncanny and unsettling. A masterful storyteller, Koontz adds special touches to increase a sense of the supernatural – voices coming from drain pipes, streetlights shattering, and even random bursts of music being heard over loudspeakers by the handful of survivors. The terror reaches a cosmic scale when Dr. Timothy Flyte recognizes the source of the supernatural events as humanity’s “ancient enemy” – a cunning being of massive size that has been feeding on mankind for centuries. I highly recommend this book if you need to stay awake all night!

"Phantoms is gruesome and unrelenting...It's well realized, intelligent, and humane."-Stephen King

They found the town silent, apparently abandoned. Then they found the first body, strangely swollen and still warm. One hundred fifty were dead, 350 missing. But the terror had only begun in the tiny mountain town of Snowfield, California.

At first they thought it was the work of a maniac. Or terrorists. Or toxic contamination. Or a bizarre new disease.

But then they found the truth. And they saw it in the flesh. And it was worse than anything any of them had ever imagined...

R. David Fulcher Why R. loves this book

If you like your scary stories mixed with a dash of science fiction, Stephen King’s The Tommyknockers is highly recommended. Set in fictional Haven, ME, the book revolves around the discovery of a spaceship buried in the woods. As Bobbi Anderson, a local writer, uncovers the ship, both she and the rest of the townspeople are physically and mentally transformed by it. Not all of the changes are welcome – Bobbi loses interest in food and starts losing hair and teeth, but in turn becomes part of a shared consciousness that makes her capable of the most amazing inventions, including a telepathic typewriter. Only Jim Gardner is immune due to a steel plate in his head, and it is up to him to stop the hypnotic spell of The Tommyknockers.

If you’re awake at night due to paranoia, then The Servants of Twilight comes highly recommended. The book creates an atmosphere of paranoia much like the movie The Invasion of the Body Snatchers. In the book single mother Christine Scavello tries to save her son from cult members of “The Twilight,” a cult led by the evil and delusional Grace Spivey. Grace accuses Joey of being the antichrist after bumping into him at a local mall. Christine enlists the help of Private Detective Charlie Harrison to protect her and Joey from the cult.
