Lena Walsh knows bodies. As the fire department's new fitness trainer, it's her job to push firefighters to their limits, keep them strong, and call them out when they're slacking. She doesn't intimidate easily. And she definitely doesn't fall for the men she trains.
Then she meets Daniel Brooks.
Controlled. Focused. Infuriatingly disciplined. Daniel treats his body like equipment and his emotions like liabilities. Lena sees through it immediately, and challenges him at every turn. What starts as friction quickly turns into something far more dangerous: awareness, attraction, and a tension that builds with every training session, every lingering touch, every look held a second too long.
Daniel doesn't mix work and desire. Lena doesn't do complicated. But the more they push each other, the harder it becomes to ignore what's happening between them.
Because some sparks don't fade.
They ignite.
