Lydia Kincaid left Boston to get away from the firefighting community—but family is number one, and her father needs her help running the pub he bought when he retired. Soon, Lydia finds it hard to resist the familiar comfort and routine, and even harder to resist her brother's handsome friend Aidan.

Aidan Hunt is a firefighter because of the Kincaid family. He's had the hots for Lydia for years, but if ever a woman was off-limits to him, it's her. She's his mentor's daughter. His best friend's sister. The ex-wife of a fellow firefighter. But his plan to play it cool fails, and soon he and Lydia have crossed a line they can't uncross.

As flirtation turns into something more serious, Lydia knows she should be planning her escape. Being a firefighter's wife was the hardest thing she's ever done, and she doesn't know if she has the strength to do it again. Aidan can't imagine walking away from Boston Fire—the job and the brotherhood are his life. But if he wants Lydia in it, he'll have to decide who's first in his heart.
