Three firefighters. One crew. A love that burns hotter than anything they’ve ever faced.

Jace Vance is the wall. Fifteen years on Engine 8, built from control and silence and the iron-clad belief that if he holds everything together, nothing can fall apart. He hasn’t let anyone close since his father died on a call — because the last time he loved someone who walked into fire, they didn’t come back.

Marek “Rook” Bell is the spark. The soft-hearted rookie who cooks for his crew, notices when everyone’s hurting, and has never once asked someone to take care of him. He fell in love with two men on his first shift and has been holding it together with cinnamon rolls and silence ever since.

Drew Liu is the anchor. Charming, reckless, the kind of man who makes everyone feel seen for ten minutes and then disappears before anyone gets close. He’s slept with half the department and been in love with exactly zero of them — until now.

When a training accident nearly kills Marek, the “we’re just crew” routine snaps open. What follows is a slow-burn, high-heat, soft-poly love story between three men who’ve been circling each other for months — and who must fight a department investigation, an anonymous complaint, and their own deepest fears to hold onto the first real thing any of them have ever had.

Chapter One: Rig Check

Jace Vance had been awake since four.

Not because the alarm went off. Not because a call came through. Because his body didn’t know how to sleep past four anymore, the same way it didn’t know how to leave a door unlocked or eat a meal without scanning the exits first. Fifteen years on the job had rewired him at the circuit level, turned him into something efficient and slightly broken, like a watch that kept perfect time but couldn’t stop ticking.

He stood in the apparatus bay of Station 8 at 5:47 AM, clipboard in hand, running rig checks on Engine 8 the way some men said prayers—methodically, silently, with the quiet conviction that if he did it right, the world would hold together for one more day.

Pump panel. Gauges. Hose bed—preconnects seated and capped, supply line flaked clean. Irons in the cross-lay. Halligan and flathead, married and strapped. Pike pole. Thermal imaging camera, charged and holstered. He checked each item the same way every time, same order, same hands, same silence. He’d been doing it alone for years. Other officers delegated. Jace didn’t delegate things that mattered.

The bay was still dark, the overhead fluorescents humming their low, pre-dawn drone. The engine sat massive and red under the lights, and Jace moved along its body the way a surgeon moves along a patient—clinical, sure, reverent.

He heard the side door open at 5:52.

Marek Bell. Of course.

The kid—and Jace called him that only in his head, because Bell was twenty-four and a grown man who’d earned his spot on Engine 8 through the academy’s toughest cycle in a decade—came through the door carrying a foil-wrapped tray that smelled like cinnamon and butter. His dark curls were still damp from a shower, pushed off his forehead in a way that suggested he’d tried to tame them and lost.

“Morning, Lieutenant.” Marek balanced the tray on one hand and saluted with the other, half-mocking, half-sincere, which was how Bell did most things.

“Bell.”

“Cinnamon rolls. From scratch. There’s cream cheese frosting if Kowalski didn’t eat it out of the container again.”

“You baked at five in the morning?”

“Four-thirty, actually. Couldn’t sleep.” Marek shrugged like that was a normal sentence and not the kind of thing that made Jace’s chest do something inconvenient. “Figured if I’m up, everyone might as well eat.”

Jace watched him disappear through the bay door toward the kitchen. The kid gave everything away—food, energy, attention, sleep—with the compulsive generosity of someone who’d never learned that the well runs dry.

He’s going to burn out giving everything away before anyone teaches him to keep something for himself.


He was checking the SCBA bottles when the bay door banged open and Drew Liu walked in fifteen minutes late, coffee in one hand, sunglasses on despite the fact that it was barely dawn and they were indoors.

“Vance.” Drew pulled the sunglasses down his nose and peered over them. “You look like you’ve been up since the Clinton administration.”

“You look like you’ve been up since twenty minutes ago.”

“Twenty-two. I timed it.” Drew grinned—that wide, easy, slightly dangerous grin that worked on everyone and that Jace had spent years building immunity to. Unsuccessfully.

Then he walked past Jace toward the kitchen, and as he passed, his hand landed on Jace’s shoulder. Brief. Warm.

It lasted maybe two seconds.

Jace felt it for ten minutes.

He stared at the SCBA gauge—4,500 PSI, full, green, good—and thought about absolutely nothing.
