Controlled Burn (Boston Fire #2)
Shannon Stacey

Jessica Broussard has no interest in leaving sunny San Diego or her cushy corner office for Boston, but her father—who happens to be her boss—dispatches her to deal with the grandparents she's never met. She's unprepared for the frigid winter, loving relatives who aren't the monsters she's been led to believe, and the hot, scruffy firefighter who lives upstairs.
At first, Jessica is determined to get back to her comfortable life as quickly as possible. All she has to do is talk her grandparents into selling their monstrosity of a house and moving to a retirement community. But she underestimates Rick's dedication—and his considerable charm. Nobody's taking advantage of his friends on his watch, even if that makes the tempting southern California girl with the long legs his adversary. Unfortunately for them both, the only thing more urgent than the matter at hand is their sizzling chemistry, and it's quickly becoming too strong to resist.
