AI The November drizzle stopped the instant Rory stepped between the two tallest monoliths. It did not taper off or catch in a canopy overhead; it simply vanished, as if she had walked through a pane of glass into an entirely different room. Behind her heel, Richmond Park lay sodden and winter-bare, smelling of wet mud and rotting bracken. Ahead of her boots, white campion and purple foxgloves stood ankle-deep in the dark.
Rory halted just inside the threshold, letting her straight black hair swing forward over her cheeks as she angled her head to listen. She did not call out. Years of navigating her ex-boyfriend’s hair-trigger tempers back in Cardiff had cured her of announcing herself in dark rooms, and moving to London had only sharpened the habit. You looked first. You located the exits. Only then did you decide whether you wanted to be seen.
She thumbed her thumb over the small crescent-shaped scar on her left wrist, an automatic grounding tic, and swept the clearing with her eyes. Seven ancient oak standing stones ringed the hidden hollow—trunks of prehistoric timber petrified into jagged grey rock, their fossilized bark ridged like frozen muscle. Most stood a clear foot or two higher than her five-foot-six frame, leaning slightly inward over the bowl of grass.
Isolde’s Grove. She had heard whispers of it downstairs at Silas’ bar for months, though she had never been foolish enough to go hunting for a Fae-touched pocket realm after dark. She wouldn't be here tonight, either, if she hadn't finished her last Golden Empress delivery shift to find a heavy cream envelope wedged into her moped’s brake lever. Inside had been a set of coordinates and a single line in cramped black ink: Midnight. The Grove. Come alone if you want to know who gave you the Heartstone.
Beneath the collar of her thermal shirt, the pendant rested cool and light against her collarbone, its thumbnail-sized crimson gem dark save for its usual faint inner glow.
Something was wrong with the clearing. She felt it before she could name it, a prickle at the base of her skull that had nothing to do with cold.
Rory pulled her phone from her waterproof jacket—the fabric still carrying the ghosts of Yu-Fei Cheung’s ginger and sesame oil—and tapped the screen. In the brief LCD glare, her own bright blue eyes stared back at her, pale and wary, before she looked up at the corner of the display. 11:58 PM. A heartbeat later, the numbers flickered to 02:41 AM, held for three seconds, and snapped back to 11:59. No signal bars. No carrier name.
She locked the screen and slipped the phone away, plunging the clearing back into gloom . Time misbehaved inside the Grove; she had expected that much . An hour among these year-round wildflowers could spit you back into London five minutes after you left, or three days late for rent. That wasn't what had her jaw clenching .
It was the flowers. And the air.
A meadow in full bloom, even under a starless sky, ought to be alive. There should have been night moths batting at the white campion, beetles clicking through the clover, the faint rustle of field mice or Richmond Park’s red deer grazing near the perimeter. Instead, the air hung dead and motionless in her lungs. Nothing buzzed. Nothing stirred. Not a single petal trembled . And underneath the heavy, honeyed scent of crushed blossoms lay something thinner and sharper, like wet ash left in a grate.
Rory took five slow steps toward the center of the hollow, testing her footing. Soft turf yielded beneath her soles with a damp whisper of bruised stems.
Shhhk. Shhhk. Shhhk.
She stopped.
Half a second later, from somewhere near the far curve of the standing stones, came one more soft, distinct sound.
Shhhk.
Rory went utterly rigid, her breath locked behind her teeth. Her father, a Cardiff barrister who treated every dinner table like a cross-examination, had raised her to dismantle panic with plain logic. Strip away superstition, Brendan Carter always said, and deal strictly with admissible facts.
Fact one: echoes did not happen in open grass.
Fact two: grass did not bend half a second after you stopped walking unless another weight had pressed it down.
She kept her gaze soft and wide, refusing to stare directly into the blackness at the far edge of the meadow, relying instead on her peripheral vision to catch motion in the dark. Nothing moved. Only the pale drift of wildflowers and the dark, hulking shoulders of the petrified oaks against a sky the color of bruised slate.
Maybe the person who had written the note was already here, waiting by the boundary to make sure she hadn't brought company. Eva would kill her if she knew Rory had walked into a park at midnight alone, artifact mysteries or not.
Then a sound drifted from the left side of the clearing.
It wasn't a footstep, and it wasn't a voice. It was a dry, rhythmic clicking, slow and deliberate, like someone tapping a fingernail against dead wood. Click. Click. Pause. Click. Halfway through the third tap, the sound changed texture, turning wet and hollow, mimicking the distant rattle of rain hitting Rory’s moped helmet—a sound that shouldn't have been able to cross the Grove’s threshold at all.
Against her sternum, the silver chain grew warm.
Rory’s fingers twitched toward her throat. Through the thin cotton of her base layer, she felt the Heartstone pulse . Once, slow and sluggish. Then again, hotter. A dull crimson stain bloomed beneath the collar of her black jacket, faintly illuminating the underside of her chin.
Her stomach dropped cleanly away.
She didn't know who had left the pendant for her, or why, but she knew the one absolute rule of its behavior: the stone did not care about Fae magic. It had never reacted to the weirdness around Isolde’s Grove or the stray glamour she’d brushed past in London. The Heartstone pulsed with warmth only when it neared a Hel portal.
If it was heating up now, Fae magic wasn't the only thing inside this boundary. Something else had torn its way in.
Rory tucked her chin down to smother the red glow with her collar and began easing backward, sliding one boot behind the other without lifting her heels from the clover. She needed the gap between the two tallest monoliths. She turned her head a fraction of an inch to confirm her bearings, counting the dark silhouettes of the ancient oak stones clockwise from where she had entered.
One. Two. Three. Four. Five. Six. Seven. Eight.
Her heel snagged on a tangle of vetch. She caught her balance without making a sound, her heart hammering a hard, bright rhythm against her ribs.
Seven. There had been seven stones when she walked in. She was certain of it; counting details was how she kept her head straight when things turned ugly.
Without moving her shoulders, she counted them again, right to left.
Eight.
Between the third and fourth monoliths on the eastern curve—less than thirty feet to her right—stood an extra column of darkness. It was narrower than the petrified oaks, lacking their flared, root-bound bases, rising straight out of the wildflowers like a charred timber. Even as Rory forced herself not to look directly at it, keeping her eyes fixed ten degrees to its left, the top six inches of the silhouette tilted sideways.
Slowly. Smoothly. Like a neck bending to get a better angle on her throat.
Around its base, the pale constellations of white campion were vanishing , winking out one by one as if dark water were spreading outward through the grass, shriveling the blooms on contact.
Then came the breathing. It didn't match a human chest, or even an animal’s. It was a single, thin inhalation that dragged on far too long—five seconds, eight, twelve—pulling the stagnant, flower-rot air inward with a faint, whistling rasp that never seemed to hit the bottom of a pair of lungs.
The gap between the boundary stones lay forty feet behind Rory and slightly to her right. To reach it, she would have to angle closer to the eastern edge. If she turned and bolted flat-out, she wouldn't make twenty paces. Predators waited for the break; they relied on panic to make prey sloppy and predictable .
Cool head, she told herself, her fingers brushing the scar on her wrist as she lowered herself into a slow, deliberate crouch. Make yourself small. Look frightened, not fast.
Keeping her gaze dropped submissively toward her knees, Rory slid her heavy aluminum flashlight out of her deep right pocket. The meadow sloped gently downward toward the western stones—away from her exit, and away from the thing standing in the dead flowers. Moving in slow motion so her elbow wouldn't jerk, she pressed the rubber tail-switch halfway in until the beam caught, trapped it against the turf with her palm so no light spilled upward, and pointed the lens down the incline.
Against her skin, the Heartstone burned like a coin pulled from a radiator, pulsing rapidly now, crimson light bleeding through her fingers where her collar gapped. Across the clearing, that impossible twelve-second inhale finally stopped. Silence coiled tight enough to snap.
Rory clicked the switch home and shoved the flashlight hard down the slope.
The metal cylinder tumbled end over end through the wildflowers, throwing wild, strobing arcs of white LED light across the western stones, slicing shadows into frantic motion.
Rory didn't watch to see if it worked. The instant the beam rolled away from her boots, she pivoted on the ball of her foot and sprinted for the two tallest oaks.
She didn't hear footsteps behind her. That was the worst part. Not a twig snapped, not a dry leaf rustled, yet the air behind her shoulder blade compressed with sudden, violent displacement, as if something massive were parting the dark like water. Over on the western slope, fifty feet out of its way, her rolling flashlight cut out mid-spin with the sharp crunch of crushed aluminum—and less than a heartbeat later, that freezing, silt-heavy rasp of breath sounded right behind her left ear.
Her hair lifted on a draft that smelled of deep river mud and old iron. The Heartstone scalded her collarbone.
Rory threw herself forward between the two towering oak monoliths, tucking her shoulder as her boots cleared the threshold.
Freezing November rain slapped her face. Mud greased her palms, skidding her knees through dead bracken and wet oak leaves until she rolled onto her back, chest heaving, dragging lungfuls of cold, exhaust-tainted London air down a raw throat.
Ten feet away, the two ancient standing stones rose out of ordinary park turf. Between them lay nothing at all—no white campion, no purple foxgloves, only soggy brown grass flattened by autumn wind and the distant orange smudge of streetlamps beyond the trees.
Nothing came through the gap.
Rory stayed flat in the mud for a full minute, shivering violently as rainwater soaked through her jeans and cooled the sweat down her spine . Beneath her collar, the fierce heat of the crimson stone slowly ebbed, receding pulse by pulse until only its faint, dormant warmth remained.
When her hands stopped shaking enough to push herself upright, she squinted at the wet turf directly between the two boundary oaks. Just inside the invisible line where the rain stopped falling, two patches of dead grass had been pressed flat into the black dirt, each the size of a dinner plate, the blades charred to grey ash where something had braced itself at the edge of the world and watched her go.
Her phone vibrated once in her pocket, reconnecting to the local cell tower. Rory pulled it out with mud-streaked fingers.
04:17 AM. Six missed calls from Eva.
Rory shoved the phone back into her pocket, turned her back on the stones without taking her eyes off them until the park trees swallowed their shapes, and walked fast toward the distant hum of the road.
