Madeline Montgomery grew up despising--and secretly loving--the roguish Gryffud "Gryff" Davies. Their families have been bitter rivals for hundreds of years, but even if her feelings once crossed the line between love and hate, she's certain Gryff never felt the same. Now, she's too busy saving her family from ruin to think about Gryff and the other "devilish" Davies siblings. Since he's off being scandalous in London, it's not like she'll ever see him again... As the new Earl of Powys, Gryff Davies planned on spending his post-war life enjoying the pleasures of London. But when an illegal duel forces him to retreat to his family's Welsh castle, he realizes the only exciting thing in the dull countryside will be seeing the fiery Maddie Montgomery. Thoughts of his nemesis sustained Gryff throughout the war; but the girl he loved to tease has grown into a gorgeous, headstrong woman - who loathes him just as much as she ever did. Will secret tunnels, dangerous smugglers, and meddling from their feuding families be enough to make Maddie and Gryff realize that their animosity is really attraction...and maybe even love?
