Even an earl needs his ride-or-dies, and Archibald Fielding-Burton, the Earl of Harcourt, counts himself lucky to have two. The annual trip that Archie takes with his BFFs Simon and Effie holds a sacred spot in their calendars. This year, Archie is especially eager to get away, until an urgent letter arrives from an old family friend, begging him to help prevent a ruinous scandal. Suddenly, the trip has become earls-plus-girls, as Archie's childhood pals, Clementine and Olive Morgan, are rescued en route to Gretna Green.

For three years, wallflower heiress Lydia Hope-Wallace has anonymously penned seditious pamphlets. And for almost as long, she’s corresponded with the Earl of Strathrannoch, whose political ambition is matched only by his charm. When Arthur’s latest letter reveals his dire financial straits, Lydia sets out for Scotland to offer him the only salvation she can think of—a marriage of convenience. To, um, herself. Unfortunately, the Earl of Strathrannoch has no idea who she is.

Before entering into a supremely-advantageous arranged marriage with James Clay, the new Duke of Earnhurst, clever, independent Lady Meg Pinwell has to see if he’s really the rake he’s rumored to be. But how is a well-bred young lady going to make sure he’s all that he seems? With the help of her Aunt Clara, they plan some discreet reconnaissance at the Duke’s country estate. Meg will pretend to be her aunt’s maid/companion to see the true state of affairs at Earnhurst Manor.
