The Tide Reversed One kiss could free him—or drown them all. #6
It smelled of mineral water, old bones, and a tide that had never seen the sun.
For one heartbeat, no one moved.
Then the door burst inward.
The sea came with it.
Not a wave. A hand. A reaching wall of green-black water full of pale fingers and seal-shaped shadows.
Callum shoved Finn toward the opening. “Down.”
Finn looked ready to argue.
Callum’s silver eyes flashed. “Down.”
Finn went.
Elias followed, then Ronan, who paused only long enough to look at Maren. That terrible, knowing gaze held her in place.
“Come,” he said.
Maren grabbed the lantern from the floor, though its flame had gone blue and useless. Callum waited at the hearth, water crashing around his knees now.
“You first,” he ordered.
“This is my lighthouse.”
“And I am not letting you drown in it.”
She almost laughed.
Almost.
Then the sea surged, and Callum’s hand closed around her waist. He lifted her as if she weighed nothing and lowered her into the dark passage.
Maren landed on slick steps with a gasp.
Callum dropped after her.
Above them, the hearthstone slammed shut.
Darkness swallowed the sound of the sea.
For a moment, there was only breathing.
Five sets.
Uneven.
Close.
The stair beneath the lighthouse was narrow, carved from black stone worn smooth by generations of secret use. Cold water ran over Maren’s boots and down into the dark. The walls glimmered faintly, threaded with veins of pale mineral light. As her eyes adjusted, she saw marks carved into the stone.
Not random.
Words.
Elias touched one with two fingers.
His face had gone very still.
“What does it say?” Maren asked.
He did not answer.
Finn, standing just below her, looked up. His wet hair brushed her cheek. The contact was accidental. Brief. Still, her pendant warmed beneath her collar, and Finn’s blue eyes darkened.
“Best not to ask questions in cursed tunnels,” he said softly. “They tend to answer.”
“Move,” Callum said from behind them.
They descended.
The staircase spiraled deeper than the lighthouse should have allowed.
Maren counted the turns until numbers lost meaning.
The air changed as they went, growing wetter, colder, threaded with the mineral taste of old magic.
The storm faded above them, replaced by a vast pulse that was not quite water and not quite heartbeat.
At last, the stairs opened into a cavern.
Maren stopped so suddenly Finn nearly collided with her.
“Oh,” he murmured.
The space beneath Blackwake Island was enormous.
A drowned world hollowed from black rock and blue shadow.
Water covered the cavern floor in shallow, glassy sheets that swallowed Maren’s boots to the ankle.
Above, stalactites hung like teeth. Phosphorescent algae glowed along the walls in soft green clusters, bright as trapped stars.
Pearl-white bones dangled from strings of silver wire, chiming softly whenever the sea breathed through hidden cracks.
Bone chimes.
Human? Animal? Something older?
Maren did not ask.
Farther ahead, carved pillars rose from the water. Some had cracked. Others leaned as if bowing under grief. Between them stretched the remains of an ancient hall—arched doorways, broken stone benches, mosaics of seals and crowned women, and a black marble dais split down the center.
“This was an embassy,” Elias said.
His voice sounded wrong here. Too loud and too quiet at once.
“Selkie?” Maren asked.
“Nhal Moran.” He stepped into the shallow water, gaze moving over the walls. “Before war. Before exile. Before betrayal.”
That last word slid under Maren’s skin.
Callum heard it too.
His expression hardened. “Read.”
Elias crossed to the nearest wall.
The stone there was carved with lines of script that seemed to move when Maren looked at them directly. Ink welled from the grooves as Elias approached, black and glossy, bleeding down the rock like fresh wounds.
Maren recoiled.
Elias did not.
He lifted two fingers and traced the first line without touching it. His mouth tightened.
“What?” Maren asked.
The cavern answered before he did.
A whisper moved through the bones overhead.
Vale.
Maren’s heart lurched.
Finn went utterly still.
Callum turned toward her.
Ronan’s scars began to glow.
“No,” Maren said.
No one had accused her yet.
She felt accused anyway.
Elias’s voice was careful when he spoke.
“This wall records the bargain between the drowned court of Nhal Mora and the keepers of Blackwake.”
“My family were lighthouse keepers.”
“Yes.”
“Not court servants. Not witches. Not—”
“Wardens,” Elias said.
The word struck the cavern and came back in echoes.
Wardens. Wardens. Wardens.
Maren shook her head. “No.”
Elias looked pained. “Your ancestor was named Alis Vale.”
Maren knew that name.
It was written in the front of her father’s oldest Bible. Scratched into the underside of the kitchen table. Carved into the brass frame of the lighthouse lens.
First keeper.
First liar.
Maren backed away from the wall.
Cold cave water swallowed her boots. The bones above her chimed.
“Read it,” Callum said.
Elias glanced at him. “Callum.”
“Read it.”
The command in his voice left no space for mercy.
Elias inhaled.
“In the seventeenth year of Queen Morwenna’s black tide, Alis Vale of the landbound blood opened the light to the sea court. She swore salt, bone, and daughter’s breath to guard what the queen could not kill.”
Maren’s pulse roared in her ears.
Elias continued, quieter.
“The four royal skins, taken under moonless bargain, shall be sealed beneath Blackwake’s heart. The princes shall wander without tide-shape, without kingdom, without return, until the keeper’s mouth chooses one and damns the rest.”
The cavern went silent.
No bones chimed.
No water moved.
Maren could not feel her hands.
“My family stole them,” she said.
Finn laughed once.
It was not humor. It was a small, broken sound that made him look suddenly older than flirtation allowed.
“Not alone,” he said.
Maren looked at him.
His face had closed.
All the careless beauty remained, but the man behind it had retreated behind locked doors.
“What does that mean?” she asked.
Finn looked toward a broken mosaic on the far wall. It showed a human woman with dark hair standing beside a crowned selkie man. Their hands were joined. Between them lay a folded sealskin.
“I trusted a human once,” he said.
Callum looked away.
Ronan’s jaw tightened.
Elias went very still.
Finn’s smile appeared like a wound pretending to be a mouth. “She had kind hands. Soft voice. A talent for looking afraid when she was lying.”
Maren’s throat tightened.
“Finn.”
He glanced at her, and for the first time since she had dragged him from the rocks, there was no flirtation in his eyes.
“She told me she loved me,” he said. “Then she sold the path to our skins for a favor from Morwenna’s court.”
Maren could not speak.
Finn looked back at the mosaic. “Your ancestor finished what she began.”
“That was not Maren,” Callum said.
His voice cut through the cavern, harsh and absolute.
Finn’s gaze flicked to him. “I know.”
“Do you?”
Finn’s eyes flashed. “Careful, brother.”
“No.” Callum stepped forward, water rippling around his legs. “Be angry. Be wounded. But you will not put centuries of betrayal on the woman who pulled you from the sea while your skin’s thief wears a crown.”
Maren stared at him.
Callum did not look at her. His shoulders were rigid, his hands clenched. Fury burned in every line of him, but it was not aimed at her.
It should have made her feel better.
It almost made her break.
“My blood kept you here,” she said.
Callum turned then.
“Yes,” he said. “And your hands saved us.”
The words entered her softly.
That was why they hurt.
A tremor rolled through the cavern.
The bone chimes rattled.
Ronan made a strangled sound.
Maren turned.
He stood near the split dais, one hand pressed to his chest, eyes gone fully black. The glowing scars across his torso brightened until the air smelled scorched. Water lifted around him in rings, shuddering away from his body. The old carvings on the dais pulsed in answer.
“Ronan?” Maren said.
He did not seem to hear her.
Elias swore under his breath. “Battle magic.”
Callum moved toward him.
The water between them exploded upward.
Callum staggered back.
Ronan’s hands curled into fists. His breathing turned ragged. Each inhale dragged a low vibration through the cavern, like drums under the ocean floor.
“Do not come close,” Ronan said.
It sounded less like warning than plea.
The black stone beneath his feet cracked.
Finn went pale. “These halls remember him.”
“What does that mean?” Maren asked.
Elias’s voice was tight. “Ronan fought here when the embassy fell. His vows were cut into him in this place. The magic is calling the violence back.”
Ronan dropped to one knee.
The water around him turned dark with ink, then red, then black again.
Maren moved before anyone could stop her.
Callum caught her arm. “No.”
She yanked free. “He told you not to come close. He did not tell me.”
“That is not logic.”
“No. It is all I have.”
She stepped into the ring of trembling water.
The cavern reacted instantly.
Every bone chime shrieked.
Ronan’s head snapped up. His eyes found hers, empty and endless, and Maren felt the force of him hit her like a winter wave.
Rage. Grief. Blood on black stone. A blade in his hand.
A crown burning. Men screaming beneath water.
A human woman at a doorway with silver keys.
His own voice, younger, breaking on a vow he could not keep.
Maren stumbled.
Ronan’s magic surged.
Callum shouted her name.
But Maren kept walking.
The water climbed her legs. Cold bit through her skirt. Her pendant burned against her throat, hotter with every step. Ronan shook as if holding back a storm with his teeth.
“Maren,” he said.
Just her name.
It sounded like surrender.
She knelt in front of him.
His hands were curled so tightly into fists that blood ran between his fingers. He was breathing too fast, chest heaving, scars bright enough to make her eyes sting.
“I am here,” she said.
His mouth twisted. “You should not be.”
“Frequently true.”
