Under The Mountain Man’s Spell

He’s spent two years fighting what he feels for her. One masked night burns it all down.

Fire captain Grayson Carter has rules. He earned them the hard way, in the smoke of a barn he burned down at twenty-five: he never lets himself want what he can’t be trusted with.
Which means keeping his hands off the town’s quiet, curvy veterinary nurse. Molly is too young for him. And far too good for him. Off the menu twice over. So he does the only thing a reclusive mountain man can do: he grits his teeth, keeps his distance, and fights his desire for Molly every single day.
Then a sexy woman in a red devil costume walks into the Halloween masquerade and asks him to take her home — and Grayson knows her before she finishes shaky request. He’d know Molly anywhere, even behind that mask.
She has no idea he recognizes her. Nor what she’s unleashed.

A steamy, small-town instalove standalone with all the tropes you crave: a growly, possessive firefighter fighting his feelings, the curvy heroine he never let himself touch, forbidden age-gap longing, forced proximity, one masked night he was never fooled by, and insta-love hot enough to burn the corn maze down.
