A Scandal In July by Kate Bateman

A summer to remember. . .
Charming bachelor Rhys Davies has absolutely no intention of falling for anyone with the surname Montgomery. The rivalry between their two families is legendary, after all, and despite all three of his siblings succumbing to the fatal attractions of the enemy, Rhys is convinced he’s immune. Until one night, when he meets Lenore Montgomery—and promptly loses his wits.

A week he’ll never forget. . .
Lenore Montgomery has wrestled a giant water snake in Brazil, chased a panther with a shoe, and survived an unfortunate shipwreck off the coast of Madagascar, but none of those things has been as difficult as seducing Rhys Davies. The stubborn man’s been ignoring her all season, so when she hears they’ll both be attending a week-long family party at his country estate, she enlists the help of her meddling relatives to prove there’s nothing as irresistible as forbidden fruit. . . especially when it might lead to true love.
