With Kelsey's fiancé in California, she is back home for three months to plan her wedding. She has colors to pick, cows to milk, and a wedding dress to squeeze into, which is why she doesn't need anybody messing with her. Especially not the guy who dedicated his whole life to making hers a joke. The guy who filled her high-school locker with frogs and hot car with cans of tuna. Kelsey always got him back, but not this summer. Things are different now. She's engaged. She's grown up. She won't fall victim to Cade’s pranks, teasing, or manly charms. If only Kelsey's dad hadn’t hired the moron to cowboy for him this summer. Now her childhood enemy is living on their ranch and seems to think they have a score to settle— and all bets are off. That Fine Line is a closed-door romantic comedy full of heart, sizzle, witty banter, and a couple of Bible swear words, but nothing that would make your grandmother blush.
