Captain Rory Kincaid clawed her way to the top. First woman to lead an elite Hotshot wildfire crew in Riverside County. Spotless record. Ironclad discipline. A rulebook where her heart should be.
Jaxson "Jax" Thorne was supposed to have her job. Seventeen seasons on the fireline. The most competent man on the mountain. Passed over for the promotion after breaking orders to save a rookie's life. Now he takes commands from the woman who replaced him — and he makes sure she knows exactly how much he resents every single one.
Three months of cold stares. Professional warfare. An attraction neither of them will name.
Then the Diablo Complex fire rewrites the rules.
When a catastrophic Santa Ana wind event sends the largest wildfire in a decade spiraling out of control, Rory's crew is cut off. No evacuation route. No helicopter. No way out. Their only option is a decommissioned concrete bunker buried in a burning hillside — a ten-by-ten box built during the Cold War and forgotten by everyone except the fire.
Seventy-one hours underground. Eighteen people. Limited water. Failing oxygen. A hand-cranked air scrubber from the 1970s. Total darkness.
And the one man Rory swore she'd never let past her walls, trapped six inches away with nowhere to go.
In the dark, the ranks dissolve. The uniforms come off. The temperature climbs past a hundred degrees. The hatred between them catches fire in a way neither of them can control — and the blaze underground burns hotter than the inferno above.
But daylight changes everything.
Back on the surface, the captain's bars go back on. The chain of command snaps into place. Two federal review boards threaten to end both their careers. Rory rebuilds every wall the bunker burned down, and Jax refuses to let her pretend that what happened in the dark didn't count.
He'll sacrifice his career to protect hers. She'll tear the rank from her own collar to keep him.
The fire above could kill them. The one between them already had.
