Duchesses in Disguise by Grace Burrowes et al

Three young, wealthy titled women decide to spend the social Season admiring the bucolic splendor of the Yorkshire Dales rather than dodging fortune hunters and scandalmongers in London. A fine plan–until the ladies’ traveling coach lands in a muddy ditch, and foul weather strands them at the estate of former officer Nathanial Stratton. As luck (or Cupid?) would have it, Nathaniel and his two friends, Kit Stirling and Greyville Trent, also have no patience with matchmaking and romance…. or so they insist.
