Regular print version previously published by Sourcebooks

"Naomi wasn't just running away from her wedding. She was riding to the rescue of her estranged twin to Knockemout, Virginia, a rough-around-the-edges town where disputes are settled the old-fashioned way . . . with fists and beer. Usually in that order. Too bad for Naomi her evil twin hasn't changed at all. After helping herself to Naomi's car and cash, Tina leaves her with something unexpected. The niece Naomi didn't know she had. Now she's stuck in town with no car, no job, no plan, and no home with an 11-year-old-going-on-thirty to take care of. There's a reason Knox doesn't do complications or high-maintenance relationships, especially not the romantic ones. But since Naomi's life imploded right in front of him, the least he can do is help her out of her jam. And just as soon as she stops getting into new trouble he can leave her alone and get back to his peaceful, solitary life. At least, that's the plan -- until the trouble turns to real danger."--
