Chapter 1: Crucifix and Grease
The air in the garage hung thick with the smell of oil and ambition. Kai Brooks had his forearms buried elbow-deep in a 2018 Mustang’s intake manifold when the rumble rolled through the bay like distant thunder. Not the everyday growl of a commuter sedan or the whine of a tuner’s toy—this was something else. Something that made the hair on his arms stand up even before he saw it.
He straightened, wiping his hands on the red rag stuffed in his back pocket, and watched the low-slung silhouette glide past the open bay door. Black as polished obsidian, the Hennessey Super Venom sat impossibly low on its haunches, carbon-fiber scoops and splitters catching the harsh fluorescent light like a predator baring its teeth. Kai let out a low whistle under his breath. That was a quarter-million dollars rolling to a stop twenty feet from his lift.
The driver’s door opened, and for a moment, all he registered was the flash of a silver necklace catching the light. Then she stood, and Kai forgot about the Mustang entirely.
She wasn’t what he expected. Sharp bob of dark hair framing a face with high cheekbones and a jaw that looked like it could cut glass. Athletic build, lean but defined, the kind of physique that came from actual labor, not a gym membership. She wore fitted dark jeans with grease stains on the knees—real grease, not fashionably distressed—and a black Henley with the sleeves rolled to her elbows, revealing forearms dusted with fine muscle and a few fading scars. The silver crucifix rested against her collarbone, catching the light as she walked toward him.
“You the master mechanic?” Her voice cut through the ambient noise of compressors and distant radios. Direct. No preamble, no small talk.
Kai tossed the rag over his shoulder, letting his gaze travel over her car before settling on her face. “Depends who’s asking.”
Her lips twitched, almost a smile but not quite. “Someone with a misfire in cylinder four and a camshaft timing issue that two other shops couldn’t diagnose.” She jerked a thumb toward the Super Venom. “You think you can handle it, or should I take my money elsewhere?”
He couldn’t help the grin spreading across his face. This woman talked about her car like a surgeon discussing a patient, and she had the confidence to match. “I can handle it. Question is whether you can handle my rates.”
“Try me.”
Kai walked past her toward the Super Venom, running his hand along the carbon-fiber fender as he circled to the driver’s side. The engine bay was pristine, not a speck of dust on the intake manifold, and he could see aftermarket fuel rails and a custom ECU piggyback that had been installed with meticulous care. He leaned over the bay, eyeing the camshaft positioning sensor. “How long’s the knock been going on?”
“Three weeks.” She stepped up beside him, close enough that he caught a faint scent of motor oil and something floral beneath it. “It’s intermittent. Worse when the engine’s cold, but it cleared up after I replaced the MAF sensor—temporary fix. The real issue is in the timing chain tensioner. Took me two weeks to narrow it down.”
Kai looked at her, genuinely impressed. Most customers came in with vague complaints like “it sounds funny” or “my check engine light is on.” This woman had already done half the diagnostic work herself, and she was right about the tensioner—he could hear the faint metallic rattle even at idle, a sound that meant the chain was skipping under load.
“You do your own work?” he asked, sliding his hand along the top of the engine bay.
“When I can.” She crossed her arms, watching him with those sharp eyes. “But this one needs tools I don’t have. Specialized timing kit, a scan tool that can talk to the ECU properly.” Her lips pressed together, and for just a second, something vulnerable flickered across her face before she smoothed it away. “And I need it done by Saturday. There’s a rally event up in the mountains, and I’m competing.”
Saturday. That gave him three days. The Super Venom’s timing chain tensioner was a nightmare to replace on the best of days, requiring the removal of half the front end. He should have told her it was impossible, that he was booked solid through next week.
Instead, he heard himself say, “I’ll have it ready.”
Her eyebrows rose, a crack in that controlled facade. “Really? Just like that?”
Kai shrugged, moving to the driver’s door to pop the hood release. “You came in with a clear diagnosis, a realistic timeline, and the balls to drive a car like this into a shop like mine. How could I say no?”
She laughed, sudden and genuine, a sound that seemed to surprise her as much as it did him. The crucifix shifted against her collarbone as she caught herself, composing her features back into that practiced neutrality. “You’re not what I expected, either.”
“What did you expect?”
“An ego.” She tilted her head, studying him. “Someone who’d say ‘sweet ride, honey’ and then charge me double because I’m a woman.”
Kai barked out a laugh, shaking his head. “Sweet ride, honey is more of a Mustang guy thing. I’m more of a ‘let’s talk about the fuel delivery issue you clearly already diagnosed’ kind of mechanic.” He walked toward the lift controls, gesturing for her to pull the Super Venom forward. “Now, you going to stand there looking pretty, or are you going to help me get this thing up so I can prove I’m worth your money?”
That earned him another almost-smile, and she slid into the driver’s seat with a fluid grace that spoke of hours behind the wheel. The engine roared to life, a deep, throaty growl that vibrated through the concrete floor and up through his boots. Kai watched her guide the car onto the lift with precise, confident movements, her hands steady on the wheel, her eyes fixed on the alignment marks. There was no hesitation in her driving, no second-guessing. She knew exactly what this car could do and exactly what she was asking of it.
The lift hummed as the Super Venom rose, and Kai ducked underneath, running his flashlight along the undercarriage. He’d worked on a lot of cars in his life, plenty of high-end ones, but there was something different about this one. It wasn’t just pristine—it was loved. Every bolt was clean, every line routed with care, every modification purposeful. This wasn’t a garage queen. This was a machine built to be driven hard and pushed to its limits.
“You race this thing often?” he called up to her.
She appeared at the edge of the lift, peering down at him through the gap. “Whenever I can.” A pause. “You don’t have to call me ‘honey’ either. It’s Amelia.”
Kai smiled up at her, catching the way the fluorescent light flickered across her face, the way the silver crucifix glinted against her skin. “Kai. And I figured as much, the way you handle the wheel.”
She ducked away, but he caught the faint color rising in her cheeks. Interesting, he thought. She’s not used to compliments that aren’t about her car or her body. He filed that away, letting it settle in the back of his mind as he focused on the task at hand.
The timing chain tensioner was exactly where she’d said it would be—sloppy, worn, the plastic guide cracked from years of heat cycles and hard use. He traced his fingers along the chain, feeling the slack that shouldn’t be there, and made a mental checklist of everything he’d need. Parts. Specialized tools. Time he didn’t have and already didn’t regret giving away.
He rolled out from under the car, finding Amelia standing at his workbench, studying the tools racked on the wall with what looked like genuine interest. She’d picked up a spark plug and was turning it over in her fingers, checking the gap with a practiced eye.
“Find something you like?” he asked, grabbing a notepad to write up the parts order.
“Just checking your work.” She set the plug down, wiping her fingers on her jeans. “You keep a clean shop. That says something about a person.”
“Says I hate losing tools in engine bays.” He scrawled out the part numbers, then looked up at her. “I’m going to be honest with you—this isn’t going to be cheap. The parts alone are going to run you around eighteen hundred, plus labor. And I’m going to need you to not call me every hour asking for updates.”
“I wasn’t planning on calling you at all.” She pulled out her phone, her thumbs moving quickly across the screen. “I’m just going to track my credit card charges and see where they go.”
Kai laughed, genuinely delighted. “You’re a piece of work, you know that?”
“So I’ve been told.” She pocketed her phone, meeting his gaze with that steady, appraising look. “Saturday, then. If it’s not ready, I’m going to be very disappointed.”
“Saturday,” he confirmed. “I’ll have it running better than when it left the factory.”
She nodded once, a sharp, decisive movement, then turned toward the office to handle the paperwork. Kai watched her go, caught somewhere between admiration and curiosity. The way she moved, the way she spoke—everything about her was controlled, deliberate, like she was constantly holding herself in check. But under the surface, flickering in the moments when she forgot to guard herself, there was something else. Heat. Fierceness.
Something dangerous.
He shook his head, forcing himself to focus on the parts order. Saturday. Three days to pull off a repair that usually took a week. He should have been stressed, should have been second-guessing his decision. Instead, he found himself looking forward to it.
When she emerged from the office, receipt in hand, she paused at the door. “One more thing.”
Kai raised an eyebrow.
“The rally’s not just for fun. There’s a cash prize, and I’m going to win it.” She tucked the receipt into her pocket, adjusting the crucifix that had slipped sideways on its chain. “So if you want to come watch, I could use someone who actually understands what they’re looking at.”
It wasn’t an invitation. It was an assessment. Another test, like the car, like the conversation. Kai passed it without hesitation.
“What time Saturday?”
Amelia almost smiled, a tiny, fleeting thing that transformed her entire face before she hid it again. “Gates open at six. First heat starts at seven-thirty.” She paused, her fingers brushing against the crucifix at her throat. “Don’t be late.”
She was gone before he could respond, the Super Venom’s engine roaring to life as she pulled out of the bay, leaving a trail of exhaust and unanswered questions in her wake. Kai stood there for a long moment, breathing in the scent of burnt rubber and something floral, watching the taillights disappear into the street.
“You got it bad, man.”
He jumped, turning to find the Mustang’s owner leaning against the fender, arms crossed, a knowing grin on his face. Kai had forgotten he was even there.
“I was just admiring the car, that’s all.” Even to himself, the words sounded weak.
“Right. The car.” The Mustang owner shook his head, laughing. “Come on, man. I know that look. That’s the look a man gets when he meets a woman who’s going to be trouble.”
Kai thought about Amelia Hartley—her sharp eyes, her precise hands, the brief flash of vulnerability when she’d talked about the rally. The way she’d almost smiled when he’d passed her test.
“Yeah,” he said softly, turning back toward the Super Venom on the lift. “I think that’s exactly what she is.”
He had three days to make her car perfect. Three days to prove he was worth more than a second look.
Three days to figure out if he was ready for the kind of trouble she represented.
The Mustang owner clapped him on the shoulder, still chuckling. “Good luck, brother. You’re going to need it.”
Kai just shook his head, rolling his shoulders and reaching for his tools. He had work to do.
