She wouldn't bend. He was built to hold the line.
Diane Kowalski inherited one thing from her father—a three-bay garage in Bridgeport with his name on the sign and forty years of honest work behind it.
When a chop shop king decides he wants her bays, she tells him to go to hell.
Now her customers' brake lines are being cut, her mechanics are quitting, and the men parked across the street want her to know she's running out of time.
Then he rolls through her door.
Union is a third-generation union man who watched corporations break every local his family ever believed in.
He found the Windy City Wolves because he needed a collective that couldn't be busted—and he's spent years making sure it won't be.
He's gruff, stubborn, holds grudges like heirlooms, and carries his grandfather's union pin into every fight.
He doesn't do soft. Doesn't do subtle. Doesn't let anyone past the picket line he's built around his own heart.
But the mechanic with grease under her nails and steel in her spine? She walks right through.
What starts as territory protection becomes something neither of them planned.
Every night in her garage, every argument about wrench organization, every moment she refuses to break under pressure pulls him deeper into a fight that has nothing to do with chop shops and everything to do with a woman he'd burn the whole South Side to protect.
But Eddie Bartosz has been swallowing shops for eighteen years, and he's not going to stop until Diane's father's name comes off that sign.
Now Union has a choice: keep his distance and stay safe... or cross every line he's ever drawn and claim the only woman who's ever made solidarity feel personal.
For a man who's spent his life holding the line for everyone else, the answer was never really a question.
His woman. His fight. His to protect.
UNION is a full-length, standalone MC romance with a gruff hero, a heroine who won't sell her father's name, and a guaranteed HEA. No cliffhanger. No cheating. Just a dangerous man who finally finds something worth more than the cause—and the brotherhood who rides with him to war.
