Down Deep by Kimberly Kincaid

Ian Gamble has a past he’d rather forget—which is exactly what he’s doing at The Crooked Angel Bar and Grill when the place catches fire. Between his active duty in the Marines and his experience as a firefighter, his instincts get him and hot, headstrong bar manager, Kennedy Matthews, to safety. But those same instincts kick into high gear when the fire is ruled an arson, and he discovers Kennedy’s got secrets of her own.

The only thing that matters more to Kennedy than her bar is her brother. When she finds out he’s in over his head with a dangerous arsonist, she’ll do anything to keep him safe—even if it means teaming up with Gamble, who’s too sharp-eyed and hard-bodied for his own good. With every step, their attraction flares hotter and the risks grow more dangerous. Can Gamble and Kennedy face their fears—and their secrets—to catch a terrifying enemy? Or will they go down in flames?
