Iron Haven (Obsidian Hearts #4)

SOME OBSESSIONS ARE BORN IN THE DARK.
OTHERS ARE FORGED THERE.

Sienna Crowe only wanted control.
A new promotion. A better body. A place to rebuild herself one rep at a time.
Iron Haven was supposed to be just a gym—discipline, not danger.
Then she met him.
Kael Ward.

Trainer. Enigma. Predator disguised as salvation.
His touch corrects. His voice commands.
And his eyes promise that once he’s finished shaping her body,
he’ll reshape the rest of her too.
But Kael doesn’t believe in coincidence.
He believes in patterns—how she moves, where she lives, who she smiles at.
Every step Sienna takes outside his sightline becomes a problem to solve.
Every man who looks at her becomes a threat to eliminate.
When the lights dim and the doors lock, the line between protection and possession begins to blur.
And Sienna must face the truth buried beneath Iron Haven’s steel and
she didn’t find him by accident.
He’s been waiting for her all along.

IRON HAVEN is a slow-burn, obsessive dark-romance for readers who crave commanding antiheroes, heroines who fight their own surrender, and tension that drags you breathless into the dark.
Violent, sensual, and relentlessly intimate—this isn’t a love story.
It’s a capture.

For mature audiences. Contains stalking, power-exchange, and morally complex themes. 18 + only.
