While driving his curricle, Rufus Solgrave, Earl of Luxton comes across Sophie Clifford lying unconscious in the road, having fallen from her horse. Not too far from home, he takes her back to Ashby, his country seat, leaving her in the care of his mother, Elizabeth, Countess of Luxton, and his sister, Lydia. Under their kindly supervision, Sophie soon begins to recover. Upon discovering that Sophie has never mixed with London society, Elizabeth invites her to accompany the family to town for Lydia’s come-out. Unhappy with her homelife and eager to sample the delights of the season, Sophie accepts.
However, her enjoyment is marred when talk of an old scandal surrounding her birth resurfaces. What’s more, her devious stepbrother, Francis Follet, has followed her to London, intent on making her his bride. Sensing Sophie’s distress, Rufus steps in to protect her from Francis’s unwelcome advances. And although neither Rufus nor Sophie are yet thinking of marriage, both soon begin to wonder whether their comfortable friendship could blossom into something warmer
