The Den of Thorns
The travel from secure safehouse to confrontation ground consumed the next hour. Headlights cut cold through the gathering dusk.
The Den of Thorns
Cassidy’s voice had cut through the manor’s suffocating silence, vibrating through the wire taped beneath her collarbone. Beckett Blackthorn sat behind his mahogany desk like a king receiving tribute, silver hair catching the amber glow of a banker’s lamp. He hadn’t offered her a seat.
“You have nerve, Miss Holloway.” Beckett steepled his fingers, wedding band catching light. “Walking into my home after what your—associate—did to my son.”
“Your son tried to kidnap my child.” Cassidy kept her hands visible on the armrests. The chair felt deliberately low, engineered to make her crane her neck upward. A power play she’d seen a hundred times in corporate boardrooms, just with more taxidermy and oak paneling. “I’m here to discuss terms.”
Beckett’s smile didn’t reach his eyes. “Terms. You believe you have leverage.”
From the van parked three blocks away, Celia’s voice crackled through the microscopic earpiece. *”Valentin and Owen are in position at the east wing. Sixty seconds to breach. Keep him talking.”*
Cassidy shifted her weight, counting the exits. One door behind her. One window to her left, reinforced glass. A fireplace that hadn’t been lit in years, judging by the pristine ash. Beckett’s desk held a fountain pen, a glass of water, and a photograph frame turned away from her view.
“I know about the gene sequence,” she said. “The one that makes Jace a threat to your bloodline’s monopoly.”
Beckett’s fingers stopped moving. The air in the room changed, thickening like storm pressure.
“Go on.”
“He’s eight years old. He can’t even shift yet.” Cassidy kept her voice measured, though her heart hammered against the wire. “But you know what happens when the northern packs learn Alistair Holloway’s grandson exists. They’ll rally around him. Your family loses control of the territory.”
“You’ve done your homework.” Beckett leaned back, considering her with fresh assessment. “Impressive for a civilian. Your source?”
“Doesn’t matter.”
*”Thirty seconds,”* Celia whispered.
“It matters greatly.” Beckett opened a drawer. Cassidy tensed, but he only withdrew a slim silver case, extracting a cigarette. He didn’t light it, just rolled it between his fingers. “Because whoever told you that much likely omitted the other half of the equation.”
“What other half?”
“The cure exists.” Beckett placed the cigarette on the desk, precisely parallel to the pen. “But it requires a living donor of the original strain. One of the Holloway line.”
Cassidy’s blood turned cold. “You want Jace’s blood.”
“I want the boy dead.” Beckett said it with the same casual cruelty of a man ordering tea. “The cure is irrelevant. What matters is that the Holloway bloodline carries a marker that predates the Blackthorn ascendancy. Every elder pack in the region swore fealty to Alistair Holloway’s father. The moment your son comes of age and shifts for the first time, those oaths become active again.”
*”Fifteen seconds.”*
Cassidy’s throat constricted. “You’d murder a child to keep a hundred-year-old promise from activating?”
“I’d do considerably worse.” Beckett finally lit the cigarette, inhaling deeply. The smoke curled between them like a serpent. “The Holloway line went dormant because your father was a pacifist who refused to claim his birthright. But the blood remembers. And when Jace reaches puberty, the packs will smell it on him. They’ll come. Wars will follow. Unless there’s no heir to rally around.”
“Then give him the cure.” Cassidy leaned forward, abandoning her calm facade. “Take his ability to shift. Make him human. He won’t be a threat to anyone.”
“The cure doesn’t remove the marker.” Beckett tapped ash into a crystal tray. “It only prevents the shift. The blood still carries the signature. The elders would sense it regardless. A crippled heir is still an heir.”
*”Breach in five. Cassidy, get clear of the window.”*
She didn’t move. “What do you want, Beckett? You invited me here. You knew I’d come. What’s the endgame?”
Beckett smiled, and it was the most terrifying expression she’d seen on him. “I wanted to meet the woman who made my son bleed. And I wanted her to understand, before she dies, that her son will follow within the month. Not by my hand—by the natural order of things. The Holloway strain carries a degenerative marker in its lunar compatibility. Without a stabilizing agent only we possess, your son’s first shift will tear him apart from the inside.”
The ceiling above Beckett exploded inward.
Valentin descended through a storm of glass and splintered wood, landing on the desk with both boots driving the surface into splinters. The banker’s lamp shattered. Beckett threw himself backward, chair tipping, but Valentin caught him by the throat before he hit the ground.
Owen dropped through the hole a second later, rifle scanning the room’s corners, already moving to secure the door.
“Hello, Beckett.” Valentin’s voice was barely human, rough with the shift barely held in check. His eyes had gone fully gold, pupils vertical slits. “I believe you have something that belongs to my son.”
Cassidy was on her feet, backing toward the wall as Owen signaled her to stay low. The earpiece crackled with Celia’s frantic breathing.
*”Multiple contacts inbound from the west wing. You have maybe ninety seconds.”*
Beckett laughed, even with Valentin’s hand crushing his windpipe. “The Holloway dog comes crawling back to the master’s house. How fitting.”
“I’m not Holloway anymore.” Valentin dragged him up, slamming him against the bookshelf. Leather-bound volumes rained down. “The cure. Now.”
“There is no cure.” Beckett’s smile was bloodied, teeth stained red. “There’s only the antidote. A temporary suppressor. Enough to stabilize the boy through his first shift, but not eliminate the marker. You kill me, and the formula dies with me.”
Valentin’s free hand closed around Beckett’s jaw, forcing his head back. “Where is it?”
“Flynn has the safe key.” Beckett’s eyes gleamed with malignant satisfaction. “And my son is very, very angry with you.”
Owen’s radio crackled. “We’ve got movement—three, no, four signatures heading this way. Armed.”
Cassidy’s mind raced. Flynn had the key. Flynn was somewhere in this fortress with a grudge and a weapon. She looked at Valentin, saw the calculation behind his fury.
“Keep him alive,” she said. “I’ll find Flynn.”
“Absolutely not.” Valentin’s head whipped toward her. “You’re extraction only.”
“He knows me. He’ll underestimate me.” Cassidy was already moving toward the door. “You have ninety seconds before this room is swarmed. I can get the key faster than you can beat it out of his father.”
Owen threw her a look that said *she’s your responsibility*, then returned to covering the door.
Valentin held her gaze for a fraction of a second. Then he nodded once.
Cassidy slipped into the hallway.
The manor’s corridors were a maze of antique furniture and bad lighting, portraits of dead Blackthorns glaring down at her. She counted doors, listened for footsteps, tried to remember the schematic Celia had shown her.
*”Left, then second right,”* Celia whispered. *”Flynn’s study has a secondary entrance through the conservatory. Motion sensors are down—Valentin’s breach shorted the grid.”*
Cassidy moved. Her heels made no sound on the Persian runners. She found the conservatory door, pushed through into humid air thick with orchid scent, and saw Flynn standing before a wall safe with his back to her.
He turned at the sound of her breath.
“Cassidy.” His voice was flat, unsurprised. The key glinted in his hand, brass and ancient. “I wondered when you’d show up.”
“Flynn.” She kept her hands visible, palms open. “You don’t have to do this.”
“I don’t?” He laughed, hollow and broken. “Your boyfriend rearranged my face. My father will have me flayed if I lose that key. I’m doing exactly what I have to do.”
“The antidote. It’s in the safe.”
“Among other things.” Flynn’s fingers tightened on the key. “You know what else is in there? The genetic research that proves the Holloway marker can be overwritten. Transplanted. Stolen.” His eyes met hers, and there was something hungry in them. “I could be the heir. I could have what your son was born with. I just need the original sample.”
Cassidy’s stomach dropped. “You want to take Jace’s bloodline.”
“I want to take everything.” Flynn inserted the key into the safe. The tumblers clicked. “But I’ll settle for the antidote and the research. Tell Valentin I’m willing to trade.”
“For what?”
Flynn pulled the safe door open, revealing a refrigerated compartment. Rows of vials gleamed inside, amber liquid catching the light. He selected one, held it up.
“For safe passage out of the country. A million dollars in untraceable accounts. And the promise that I never see any of you again.”
Cassidy heard the gunshot from the study before she saw the consequences.
Three rounds. Controlled. Then silence.
*”Valentin’s down!”* Owen’s voice screamed through the earpiece. *”Repeat, principal is down—Cassidy, get out—”*
The line went dead.
Flynn saw her face change. He grabbed three vials, shoved them into his coat pocket, and bolted toward the conservatory’s eastern exit.
Cassidy didn’t think. She ran.
She hit the study door at a sprint, found chaos. Owen was crouched behind the overturned desk, exchanging fire with figures in the hallway. Beckett lay crumpled against the bookshelf, blood spreading across his white shirt. And Valentin—
Valentin was on his knees, one hand clamped over his ribs, blood seeping between his fingers. His gun lay three feet away, out of reach.
He looked up as she entered, and his eyes were human again. Human, and full of something she’d never seen in them before.
Fear.
“Cassidy.” His voice was a rasp. “Flynn has the antidote.”
“I know.” She crossed to him, dropped to her knees, pressed her hand over his wound. Warmth spread beneath her palm. “I saw him. He wants to trade.”
“No trades.” Valentin’s hand covered hers, squeezing. “He’ll kill you. He’ll kill Jace. The only option is—”
“Is dying.” Cassidy’s voice broke. “You don’t get to do that. You don’t get to leave me with that choice.”
“Covering fire!” Owen shouted. “Now or never!”
Valentin’s gaze held hers. Something passed between them, wordless and absolute. Then he nodded.
“Help me up.”
She did. He swayed, caught himself, retrieved his weapon. Owen threw a flashbang through the doorway, and the room went white and screaming.
They moved.
Through the smoke, through the chaos, through the back corridors Celia guided them toward. Valentin leaned on Cassidy, each step a battle, blood leaving a trail they couldn’t hide.
They burst through a service entrance into the night air. The van was there, Celia at the wheel, side door already sliding open.
They piled in. Tires screamed. The manor shrank in the rearview mirror.
Celia was crying. “He—the signal cut out, I thought you were—”
“We’re not.” Cassidy pressed a cloth against Valentin’s wound, felt his pulse thready beneath her fingers. “But we don’t have the antidote.”
Valentin’s eyes were closed, face gray. “Flynn will contact us. He wants the trade. We’ll be ready.”
“Ready how?” Cassidy demanded. “You can barely stand.”
“Because I’ll have something he wants more than money.” Valentin opened his eyes, and the gold was back, burning cold and certain. “I’ll have the only leverage that matters.”
He reached into his jacket, withdrew a photograph. The one from Beckett’s desk, turned away from her view.
It showed a woman. Young. Dark-haired. Pregnant.
“Beckett’s daughter,” Valentin said. “Hidden away after she refused an arranged marriage. Flynn doesn’t know she exists. But if I have to—”
“Valentin.” Cassidy’s voice cut through his spiral. “We don’t burn innocents.”
He looked at her. The fire in his eyes warred with exhaustion, with pain, with the desperate love of a father who would burn the world for his son.
“Then what do we do?”
Cassidy took the photograph from his hands. She studied the woman’s face—the wariness, the hope, the same stubborn set of jaw she saw in her own mirror.
“We find her first,” Cassidy said. “And we ask for help.”
The van hurtled through the night, carrying them away from the Den of Thorns, toward whatever dawn would bring.
Celia’s hands trembled on the wheel. Owen checked his remaining ammunition. Valentin’s blood soaked through the makeshift bandages.
And in a conservatory three miles behind them, Flynn Blackthorn opened a refrigerated case and began to plan.
The first vial of antidote sat cool in his palm.
The second held something far more valuable.
The third held a solution that would change everything.
He smiled, blood staining his teeth, and began to dial.
*”Give me the antidote,”* Valentin snarled, *”or I swear on the moon, I will burn every Blackthorn into ash—starting with you.”*
