Chasing Her Fire by Claire Kingsley

Sexy firefighter Logan Bailey is an expert at putting the wet stuff on the hot stuff—on and off duty. But he just did the unthinkable, and it wasn’t trading in his tube socks. He slept with his nemesis. His mortal enemy. The crazy redhead he loves to hate. Cara Goulding.
And no matter how much he wants to lie to himself, he has to admit, it was mind-blowing.
Cara will not be tempted by the one night she spent with prince dickhead—even if her traitorous body remembers every earth-shattering moment. It was a mistake and she’s stronger than that. She’ll just keep avoiding him and pretend it didn’t happen.
But the feuding small town of Tilikum might not be big enough for the both of them. Avoiding each other isn’t working. And with every moment they’re forced to spend together, the sparks get hotter, the flames grow brighter, and the tension borders on unbearable.
Until they both reach their breaking point and their fiery relationship explodes.
