To her number-one enemy?

After the shocking discovery of her family's true identity, a sheep show in Las Vegas ought to be mundane for Dahlia Fortune. That is, until the Texas rancher takes a spontaneous walk down the aisle with her new next door neighbor and childhood rival, Rawlston Ames! A quick annulment's clearly the way to keep this whirlwind marriage from becoming front-page news back home. But why can't Rawlston cut ties with a woman who's always been alternately infuriating--and infatuating?
