This is a real marriage of inconvenience.
Viscount Penvale has been working for years to buy his ancestral home, Trethwick Abbey, back from his estranged uncle. So, of course, he's thrilled when his uncle announces that he is finally ready to sell . . . but with one major caveat: Penvale must marry his uncle's ward, Jane Spencer.
When the two meet in London, neither is terribly impressed. Penvale finds Jane headstrong and sharp-tongued. Jane finds Penvale cold and aloof. Nevertheless, they agree to a marriage in name only and return to the estate.
