When Jamie Andrews moves in with a house full of firefighters, things start heating up fast. Battling the wilderness of rural Montana, these guys are always charging into danger--for a living, for duty, for the rush--and since Jamie is a psychiatric nurse, they fascinate her analytic mind. She can't help but fixate on Calvin, a grumpy, enigmatic smoke jumper ten years her senior. She makes playfully tormenting him her pet project, trying to get him to open up. It turns out he gives as good as he gets.

When something smoldering between them sparks, they'll have to keep it quiet, which makes Jamie start to wonder about Calvin's secret, the one he won't explain. She'll learn more after life pulls them apart. But as she follows the truth like a trail of flame into the dark, will it lead her to hearth and home with Calvin...or will it all go up in a blaze?
