Tagline: An assassin bound by obedience. A detective marked for death. A cartel war with no survivors.

Book Description:

Von Schlange thought she’d escaped her past. Now Black Nova owns her—an elite, off-the-books task force where obedience is survival and failure means death. As their newest assassin, she’s unleashed on targets tied to Jaxon Ryker, a drug lord buried deep in the Alaskan wilds.

Her partner, Xander Holt, a former Navy SEAL with ice in his veins, lives by the same brutal code: no attachments, no lines crossed. But as missions turn bloody, the fragile boundary between partner and lover begins to blur—and desire becomes its own kind of danger.

Across the country, Detective Anaya Nazario faces a nightmare of her own. A synthetic “zombie drug,” deadlier than fentanyl and immune to Narcan, is ripping through Los Angeles. Her investigation exposes a network of dirty cops shielding Ryker’s empire—and puts a target squarely on her back.

Two women on opposite fronts. One war against corruption and cartel power. And a single truth—every betrayal leaves a body behind.

Explosive, unrelenting, and razor-sharp, The Serpent’s Order propels the Serpent Series into its most dangerous chapter yet—where justice is a myth, and survival comes at a price paid in blood.

Read an Excerpt:

 

Darkness pressed against her eyes. The air carried no warmth, only a damp cold that burrowed into her marrow. The metallic taste on her tongue sharpened. Air scraped colder against her throat. Every nerve screamed awake as the chemical fog bled out of her veins. It was easy to fend off the hazy pull of delirium when it felt like she was sitting in an ice box. Frigid salty air wrapped her in an arctic grip, numbing her body. The sound of the seas never betrayed its location, offering no clues as to her whereabouts until the blackout hood was lifted.

Her surroundings winked awake, blurring slowly into focus. Faint traces of soot and aged timber amplified the cabin’s solitude. As her vision sharpened, the first thing she saw was the rugged glaciers looming beyond the drafty windows. Snow consumed the landscape, a frozen expanse as thick as packed sugar, burying the world beneath at least twenty inches of wintery silence. At a distance, she could hear how the ocean roiled, a wild, restless beast, while the bitter subzero terrain stretched in stark harmony with the gray horizon.

Groggy, her eyes roamed in search of Zeus, panic setting in, forcing her heart to quicken until she spotted him across the room in a dark corner. Her head felt like a thousand-pound weight pressed down on her skull, each pulse of pain a hammer striking her temples. She found herself passed out on a lounger that looked to be a decade old—at least her kidnappers, or rather, her new boss—had the courtesy to leave her somewhere relatively comfortable. At the sound of her steps, Zeus lifted his head, tail thumping against the rickety wooden floorboards, though not quite making it to his feet.

It looked like she wasn’t the only one trying to shake herself out of the cocktail she’d been injected with, as Zeus tried to drag himself up. She knelt beside him and massaged his legs, trying to coax circulation back into his limbs. After a few minutes, Zeus soldiered to his feet, the kneading doing the trick. Von exhaled, tension ebbing at the reassuring presence of her loyal companion. She ambled back to the kitchen, taking in her surroundings while Zeus kept time with her steps. A thin film of dust coated the kitchen counters and cupboards, telling her that time had been the lonely cabin’s sole friend for a long while.

She rooted around, discovering there were enough dishes for one person, and the fridge had been stocked with salads and fruit. At least her mysterious employer had the decency to respect her food preferences. They even left a bowl of dried dog food and water for Zeus. How thoughtful. She smirked at their attention to detail as she headed to the bedroom—and then she saw it.

Sitting dead center on the bed, the phone was waiting for her.

Sleek, black, and unbranded—just a smooth slab of technology with no markings or logos, nothing to indicate who made it. While it appeared to be just another typical high-end smartphone, Von knew better. This wasn’t an ordinary device. It was a leash. She picked it up. Lighter than she expected. No buttons, no ports, no removable SIM card. Completely sealed. The kind of hardware designed to be untouchable, tamper-proof. Not to be trusted. The screen stayed dark for a ten-count before flickering to life, awakened by a simple touch. The interface was equal parts minimalist and sterile.

Nothing personal. No apps. No browser. Just a lone notification, already there.

“Welcome to Black Nova.”

She flipped it in her hand, examining it. There wasn’t even a password prompt, fingerprint, or facial recognition scan. Von wasn’t logging in. She was already in—immediate access like it knew her. Then she remembered where she’d seen one before: Jefferson Pierce. Former Marine-turned-hacker, an asset for the FBI. Asset. The word twisted in her stomach, acidic and biting. She recalled the words—“federal asset”—before her world went black. Right before they took her.

“Silent Circle—” Jefferson had called it.

“A what?” She recalled how her brows had knitted together, confused over the unfamiliar phone. “Never heard of it.”

“Military-grade. Locked down tight. End-to-end encrypted calls and messages.”

“Sounds a bit paranoid,” Von had said.

“For what I do—I gotta be. Safest, most private phone out on the market.

She recognized it now. Its black matte finish and elegant, no-nonsense style. But it wasn’t hers—it was theirs. A direct line to the people who had dragged her into this. Her permission not needed. Her choices, her next movements, her next breath would be dictated, assigned. The second she thought this, the phone rang. She stared at it, letting it ring three times before quietly answering.

“You’re awake. Good. Commander Lucian Cain here, in case your memory needs a little reminder,” a calm, authoritative voice began. “Let’s see if we didn’t make a mistake bringing you into the fold.”

“Where the hell am I?”

“Kodiak Island.”

“Fucking Alaska?”

“Impressed you know your geography—most people don’t know where Kodiak Island is,” Cain said. “Before we officially begin, you must complete our test.”

“And if I fail?”

“Don’t think failure’s in your DNA,” he said, then switched to German, “Schlangenfrau.”

She hadn’t intended to assume the title of the Serpent Woman, not before the brutal attack that dragged her to the edge of death. Her guts shredded, body mutilated and left infertile, stripped of the capacity to bear life. A monstrous snake-like crimson keloid scar now etched its path along her abdomen, sewn back up like an object in a sterile lab—efficiently reconstructed like a modern Frankenstein experiment, an uncanny patchwork that left her hollow.

Von Schlange—Schlangenfrau—the Serpent Woman had become her signature.

Elmer Kelton’s The Blessing by John Bradshaw ~ @RABTBookTours #RABTBookTours #ElmerKeltonsTheBlessing #JohnBradshaw #HistoricalFiction

Elmer Kelton’s The Blessing by John Bradshaw

Western Adventure, Historical Mystery

Date Published: 12-03-2025

Publisher: Devil's Claw Press

About the Book:

Hewey Calloway, Elmer Kelton’s favorite footloose cowboy, has always been known to have a generous nature, readily giving to those in need. Time has finally mellowed Hewey and given him some wisdom that was lacking in his youth, but deep down, he’s still the same old Hewey. In this sequel to The Smiling Country, a beneficiary to one of Hewey’s past generosities pays him back, and with interest. Knowing Hewey would decline a monetary repayment, he is gifted land back in Upton County.

Trouble is, it was bought from his old adversary, Fat Gervin, who is still as crooked as ever. Gervin finds a seeming loophole in the contract and tries to pull another fast one on Hewey, who is fed up with Gervin’s endless treachery. Tensions rise, and when Gervin is shot, it’s Hewey who’s on the hook for the crime. But things are never as they seem, and it’s up to an eclectic cast of characters to sort it out, and for Hewey to learn what’s really important in life.

Written by longtime journalist turned novelist John Bradshaw, who was selected by The Elmer Kelton Estate to continue the Hewey Calloway tradition.

 

About the Author:

John Bradshaw is a native of the small town of Abernathy, Texas. He is an award-winning journalist with well over a thousand published stories. Elmer Kelton’s The Familiar Stranger, co-authored with Steve Kelton, is his first book.

Bradshaw attended South Plains College followed by Texas Tech University. He spent several years shoeing horses for a living as his writing career progressed.

While the desire to write books was always there, Bradshaw first pursued a career in journalism. He wrote numerous stories for ranching, horse and horseshoeing magazines.

Growing up, Livestock Weekly came in the mail once a week, as it does for most in the livestock industry. Writing for Livestock Weekly was always a goal, and in 2005 Bradshaw’s first story was published. It was a profile of Brownie Metzgar, a humorous cowboy still working in a feedlot while in his late 80s.

In 2007 Bradshaw accepted a fulltime position with Livestock Weekly. While with the paper he had over a thousand stories published, as well as enough market reports to give him permanent nightmares.

Horses have always played an important role in his life. The son of a horseshoer, he has spent a significant amount of time either on or under a horse. He still shows in both ranch horse and reined cow horse competitions.

He and his wife, Sara, live outside Abernathy. Sara owns an architecture firm, SK Architecture Group, and they raise Spanish goats, hair sheep and cattle.

In 2013 the couple had a stillborn son, Fox Joaquin Bradshaw. After several years of heartbreak they adopted an infant boy, whom they named Julian Boone Bradshaw. Boone died in his dad’s arms following an accident at the barn five days before his sixth birthday.

Incubus by Jonathan Wright ~ @RABTBookTours #RABTBookTours #Incubus #JonathanWright #DarkFantasy

Incubus by Jonathan Wright

 

Dark Fantasy/Horror Action Romance

Date Published: December 23, 2025

Publisher: ‎Changeling Press LLC

Life -- and love -- with a man who fights nightmares is bound to be… different.

Smart, capable, and lethal, Sarah Fenton never needed rescuing -- until she met Joe Horn and his horrifying nemesis, the muck-drippy-thing. Together they defeated that nightmare, and for the first time in decades Joe could stop running.

In the process, Sarah discovered her weakness -- Joe. The hard-as-nails woman becomes Joe’s willing sub -- his slave girl. Joe is a perfect Dom, but Sarah has even darker fantasies -- lurid, sensual and totally submissive. Sometimes, they even come to life.

Now one of them is stalking her, and she feels the awful temptation of nightmarish pleasure. The darker the fantasy, the more intense the pleasure. Pleasure stronger than any drug. Pleasure that threatens to drown her. The pleasure of surrender… to an Incubus.

Warning: This is a Razor’s Edge Erotica short story. Expect limited plot and character development, and lots of heat. If you’re looking for a lengthy plot driven erotic romance, this is not it!

About the Author:

Jonathan Wright retired to the northeast, where he is surrounded by family and trees in about equal numbers. In his free time he enjoys thinking up erotically terrifying situations for his characters, who insist they don’t like that sort of thing. When he isn’t writing about slavering fangs in the dark he does weird-ass paintings.

He has a daughter who will admit to the relationship under duress. He puts up with her because she makes great cookies.

We don't know why she puts up with him.

Cole for Christmas by Treva Harte ~ @RABTBookTours #RABTBookTours #ColeforChristmas #TrevaHarte #ChristmasRomance

Cole for Christmas by Treva Harte 

A Friends to Lovers BDSM Ménage

Christmas / Romance / Comedy

Date Published: December 23, 2025

Publisher: Changeling Press

Sarah has a secret -- she wants her best friend Cole. Cole wants Jeff. And Jeff? Surprise! He wants them both.

About the Book:

Cole is wild, funny, impulsive, and Sarah’s best friend. She doesn’t understand what he gets out of submission, but she’s not going to let Cole get hurt the way he has in the past. So when she discovers his new dom is Jeff, the jerk who helped kick her out of her undergraduate program, she knows she has to intervene.

But when she sees Jeff again, she’s confused. He says he wants Sarah to be Cole’s Christmas present, and she’s stunned. She and Cole are just friends, aren't they? Amazingly, Cole seems to want her as much as she secretly has wanted him. The even bigger surprise? She realizes she wants Jeff too.

Even if she could have them both, this is supposed to be temporary. It’s too bad she’s only allowed to have Cole for Christmas.

Read an Excerpt::

Copyright ©2025 Treva Harte

“What’s wrong with you, Cole?” Sarah stared at her friend over the flimsy coffee container. “You have to go pee pee? You’ve been twitchy ever since we got here.”

Cole laughed and gave her the finger. He opened his mouth as if to give a smart-ass answer but then bent over his latte instead. Not looking at her, he carefully blew on it and took a sip.

Sarah settled back. Cole was obviously dying to tell her something, and she knew from experience all she needed to do was sit. If he waited more than ten minutes before spilling everything, he’d probably keel over from the strain.

The clatter of students milling around the student union coffee shop made the silence less noticeable. They continued drinking.

Two minutes of just downing caffeine. Impressive. Cole was hanging tough.

He shifted again in his seat and shut his eyes, grimacing. Sarah frowned, suddenly a little concerned. Cole was a genius -- a real, measured-by-testing genius -- but that didn’t mean his emotional IQ always matched his intelligence. She was sure it was a challenge to be five to ten years younger than his academic peers, and Cole didn’t always meet that challenge. In fact, Cole could be kind of a pain in the ass. Right now he was acting like he had a literal pain there.

Oh. Ohhhh, boy. He might actually have one. Please God, no. She might have to venture into TMI territory to find out.

Cole had been more than forthcoming about his sex life in the two years they’d been in grad school together. That was a problem for him. Younger and smarter in some things had made him vulnerable in others, especially since he was open about his sexual preferences and desires. Gay at the university was one thing; gay and dedicated to BDSM was another.

“Has someone hurt you?” She hoped that question would get the job done. Sarah could be more direct, if need be, but she also probably didn’t want to know all the particulars.

“No.” His prompt answer was a relief. Of course, he had to add, “Not any more than I want to be.”

“Ooookay.” Sarah set down her cup. Sometimes a friend had a duty to ask more even if she’d so much rather not. “Have you met some new dom?”

“You know I have. I told you about him.” Cole didn’t look up from his latte, but he didn’t sound reluctant to answer.

“You mentioned you’d met someone new at a club a few weeks ago, but you didn’t say anything more.” That wasn’t like her Cole at all now that she thought about it. “Is that the guy?”

“Fuck yeah. I was incredibly lucky that night. He hardly ever goes to clubs. Says they’re too fake for his tastes.” Cole squirmed again. “He isn’t into scenes. Not public ones.”

“So you’ve been -- um -- doing things outside of clubs?” Sarah wasn’t sure which sounded more dangerous. Cole wouldn’t know danger if it bit him on the butt. Especially if it bit him on the butt.

“At his place. Sarah, it’s… intense. And really sexy.” Cole grinned at her. “That’s all I’ll say unless you want me to go on. I know how you get.”

“And I know how you get, so thanks for shutting up.” She grinned back at him, and Cole shifted his weight again. Sarah sighed. “All right, Cole. Why are you acting this way? Something is going on.”

Cole leaned over, then glanced around to make sure no one was listening. Oh God. He felt the need to keep something private. This was going to be a doozy. 

About the Author:

Not content with that, she added a J.D. Since then she's added a husband, also an attorney, and two children to her collection. She's continuing her ways as an overachiever, writing her wonderfully offbeat tales of passion and possibilities -- in her spare time.
