Free to Protect by Tracey Jerald

Captain Brett Stewart is a second-generation firefighter. His life is irrevocably changed when he enters a burning building only to be trapped. Now, recovered from his injuries, he’s eager to don the gear that failed him and get back to work.
He never expects his blood to ignite when he sees a swoosh of gray across a crowded fundraiser.
He has to meet her.
Local business owner Jillian Beale knows all too well fire can destroy everything in its wake. From a childhood of uncertainty, she was content until her safety net incinerated one afternoon. Then she has no choice but to fight to protect her future.
But after Brett leads her out onto the dance floor, her vision for the future goes up in smoke.
After all, who better than she knows that touching fire burns?
