Hostile Ice Chemistry

Chapter 1

Nadia POV

The gale off Lake Superior carried the sting of shaved glass, biting through the seams of my coat before I cleared the heavy double doors of the Barrow Ice Arena.

Inside, the air was hardly warmer. It hung dense and still at twenty-four degrees, thick with the sour grease of the Zamboni’s propane exhaust, the ammonia tang of the chilling pipes, and the sharp bite of menthol liniment rising from the rubber floor mats.

Overhead, forty-foot cedar rafters groaned beneath the weight of an October blizzard gathering over the Upper Peninsula, their dark timber lost in the glare of buzzing halogen banks.

I shifted my grip on the aluminum field case, the metal handle biting cold through the knit of my glove. Under my other arm, two binders of kinematic diagnostic charts dug hard against my ribs.

His right arm hung motionless in a black neoprene sling, his posture collapsed forward against the gray railing.

Seven months ago, Gavin had possessed an explosive first step and a clean ninety-mile-an-hour wrist shot.

Now, three surgical pins held his collarbone together, and his athletic scholarship had been reallocated to incoming defensemen who had not been slammed into the end-boards by a six-foot-four freight train wearing number eighty-eight.

A bitter ache clamped around the base of my throat. I tore my eyes away, focusing on the scuffed linoleum leading to the department offices.

Gavin’s shattered clavicle had taken my senior capstone project down with it.

When his season ended on the operating table last March, our joint grant for velocity-load biomechanics evaporated.

That left me with a fourteen-day overdue notice from the university bursar sitting folded in the back pocket of my jeans, and an empty bank account that made my stomach cramp every time I checked my phone.

My father had already sold his spare mig-welder and drained the last two thousand dollars from his shipyard pension to cover my tuition deposit in August. His hands—scarred, rough, missing half the index finger from a dry-dock crane failure—had handed me that cashier's check with an unyielding order: Finish it, Nadia.

Don't you dare come back to the yard with a wrench in your hand.

I swallowed down the dry heat in my esophagus. Failure was not an option. I had twenty minutes before my scheduled grant review with Dr. Evelyn Morris, and my hands were so cold my thumb ring spun freely against the knuckle.

Down on the main sheet, the crack of composite carbon against vulcanized rubber echoed through the empty arena like a rifle shot.

A lone skater was working the neutral zone.

No helmet. Black practice jersey soaked through between the shoulder blades, clinging to the thick slab of his upper back.

He gathered a loose puck off the red line, opened his hips with fluid balance, and drove a wrist shot into the top-right corner of the empty net with enough violence to make the iron frame shudder against the concrete footings.

Killian Castaneda.

Campus royalty. The NHL scouts’ golden boy. The licensed butcher who had driven Gavin through the acrylic glass and skated away with a two-minute minor.

He retrieved another puck from the corner, his jaw set in a hard, square line, dark hair plastered against his forehead with sweat.

Even from forty feet away, the heat radiating off him seemed to warp the freezing mist hanging over the ice.

He moved with a heavy, predatory economy, using his stick as a precision weapon, his eyes flat and devoid of joy.

I tightened my fingers around the binder until the plastic groaned, spun on my boot heel, and marched down the service corridor toward the athletic science suites.

The corridor behind the home bench was narrow, dimly lit by wire-caged yellow bulbs, and paved with grooved black rubber designed to protect skate blades. The walls smelled of stale damp pads and wet cedar.

I had my head down, flipping through the sensor calibration logs to ensure my baseline calculations were intact for Dr. Morris, when the heavy steel fire door at the end of the hall swung inward with a dull hydraulic wheeze.

I took two hurried steps forward, rounding the blind corner by the stick-drying rack.

Impact.

It was like hitting an oak beam covered in frozen wool.

The breath left my lungs in a short, ragged whistle.

My shoulder struck solid muscle, the collision knocking my boots sideways off the slick rubber tread.

The aluminum case slipped from my numbed fingers, clattering against the concrete baseboard, while my binders splayed across the floor, loose telemetry sheets scattering into the dirt.

A broad, calloused hand clamped around my upper arm before my hip could strike the deck.

The grip was uncompromising, broad fingers biting through my waxed coat with enough force to halt two hundred pounds of momentum, let alone my one hundred and twenty.

"Eyes up, Gregory," a voice grated above me.

The register was low, dragging across gravel, rough from breathing sub-zero air.

I looked up.

Killian stood planted on his skate guards, towering six inches above me, his broad shoulders blocking the hallway lights.

He wore only his black compression top and padded track pants, his collarbone glistening with sweat that cooled into vapor in the drafty corridor.

A jagged, two-inch silver scar cut through the arch of his left eyebrow, pulling the skin tight over high, blunt cheekbones.

He smelled of crushed cedar needles, the bitter tang of friction tape, freezing iron, and black pepper. The raw heat pouring off his chest was suffocating in the narrow space.

His fingers remained locked on my bicep, thumb resting directly against the inside seam where my pulse hammered against his skin.

"Let go of me," I said, the words scraping out past a suddenly dry tongue.

Killian didn't release me. His dark eyes flicked down to the scattered papers on the rubber matting, noting the force-vector graphs and velocity curves with mild, insolent disinterest. Then his gaze dragged back up, settling directly on my mouth before meeting my eyes.

A knot of muscle jumped rhythmically along his jawline.

"You're in the team lane," he said, not moving an inch. His voice dropped an octave, the clipped imperative designed to make underclassmen back into the drywall. "Watch where you drop your homework."

Adrenaline surged into my fingertips, pushing the cold out of my blood. I planted my boots and jerked my arm back against his grip. His fingers held for one stubborn, insolent second—testing my resistance—before he let go, his hand dropping to his side.

"This is a shared service thoroughfare, Castaneda," I snapped, crouching down to gather my scattered data sheets before his wet skate guards could ruin the ink. "Not your private runway. Some of us actually have work to do in this building that doesn't involve breaking bones."

He didn't bend to help. He stood over me, arms crossed over his chest, his biceps straining the dark fabric of his shirt. A faint, mocking smirk touched the corner of his split lower lip.

"Still whining about Mercer?" he asked, his tone flat, without a shred of remorse. "He leaned into an open-ice hit with his head down. That's not a crime, Gregory. That's poor peripheral vision."

My fingernails dug into the edge of a chart, crumpling the heavy bond paper. I rose to my feet, squaring my shoulders, forcing myself not to step backward even though the sheer physical mass of him crowded out the air between us.

"It was an illegal check from behind, and you know it," I said, my voice dropping into a razor-sharp clinical cadence.

"You carry a five-degree inward torque on your right hip every time you decelerate to make contact.

You're compensating for a structural imbalance.

You hit him dirty because you couldn't adjust your edge in time. "

The smirk vanished from his mouth.

His pupils dilated, the black swallowing the dark amber of his irises.

The muscle in his jaw locked hard, turning the angle of his face to stone.

He took a single half-step forward, cutting the distance between our chests to three inches.

The heat radiating off his skin washed over my face, carrying that scent of cedar and cold sweat.

"You think you know how I skate?" he murmured, the gravel in his throat rough and quiet.

"I have two years of your kinematic game data on my hard drive," I replied, tilting my chin up, exposing the rapid thrum of the vein in my throat.

I refused to look down. "You're a biological wreck waiting for a torn groin, Castaneda.

The only reason the NHL hasn't written you off yet is because you're lucky. "

For four agonizing seconds, neither of us breathed. His eyes dropped to my throat, tracking the frantic beat of my pulse, then dragged up to lock onto mine. His chest rose and fell in a slow, controlled rhythm that contrasted brutally with the frantic racing of my own heart.

"Be careful with that tongue, Gregory," he said softly, his voice a low vibration that seemed to settle in the floorboards beneath my feet. "One of these days, you're going to say something you can't back up with a graph."

He stepped around me, the heavy rubber of his skate guards squeaking on the wet matting, his shoulder brushing mine with intentional, unyielding weight as he passed.

The fire door swung shut behind him with a metallic bang that echoed down the empty hall.

* * *

My hands were shaking so hard I could barely slide the scattered papers back into the binder rings.

I stood in the cold hallway, breathing through my nose, trying to force the copper tang of adrenaline from the back of my mouth. My bicep still throbbed where his fingers had clamped down—not with pain, but with a lingering, localized heat that felt burned through the fabric of my coat.

Arrogant. Brutal. Entitled.
