Recipe for Rivals by Kasey Stockton

She thought she could steer clear of romance in a town full of cowboys, but then she met the fireman.

After signing divorce papers and leaving her New York life behind, Nova Walker needs a refuge. She finds it in small town Texas with her Aunt Gigi, along with the opportunity to earn her keep working in Gigi’s diner. Since she’s going to Arcadia Creek, Nova expects the cowboys, but she doesn’t expect the extremely attractive firefighter who—living up to his fiery title—seems to butt heads with her at every turn.
With his charm and cocky attitude, Dusty Hayes—as hickish as they come in this backwater place—has a knack for pushing Nova’s buttons and propelling her competitiveness into overdrive. Friendly battling with Dusty gives her a break from her insurmountable trials, but though his antics soon change from teasing to flirting, Nova can’t allow her walls to crumble. Because the last time they did, she lost everything.
And with two small kids depending on her, Nova will never allow that to happen again.
