Marriage and happily-ever-after are for suckers... Joe Whelan was fooled once on the way to the altar, and the Irish doctor isn't about to be an eejit over a woman again. Especially not one who witnessed his broken-hearted humiliation years ago. He won't be swayed by the sparks that fly whenever his eyes meet MacKenna's or distracted by her sweet kisses. The only thing Joe cares about is preventing his sister from making the biggest marital mistake of her life. MacKenna Jones loves a good wedding-so long as she's sewing the bride's gown, not walking down the aisle herself. Falling for Joe Whelan's sexy bedside manner wasn't on the cards, neither was a seven-day road trip with him to Las Vegas, the Marriage Capital of the World. When the stakes are so high, will these two gun-shy cynics ever say I Do?
