Knot the Firefighter's Secret Omega

Leah Vance has been passing for a beta since she was fourteen. No scent, no heat, no problem — as long as nobody looks. She keeps a tin of citron-and-cotton scent cards in her locker and a practiced shrug on her shoulders. Fire Captain Whit Hollis has known the truth for two years. He pulled her out of a house fire and smelled nothing at all. He's never said a word. Then someone starts burning down Cattail Creek's old mill district — every building marked, every fire set where a bonded pair once lived. The task force throws Leah and Whit into the same room once a week, and the secret starts to feel less like a shield and more like a wall. When Leah's the only person in town who can scent the accelerant residue, keeping quiet stops being an option. A small-town omegaverse romance with a firefighter alpha, a heroine who is not scentless but scent-free, and a bite on the courthouse steps.
