The Duke's Got Mail (England's Sweethearts, Bk. 2)

Anonymous love letters are all well and good… until you discover you’ve been flirting with the enemy.
 
Eleanor Wright is the best compositor in London and in high demand with every printing press in town. But when whispers spread of a new machine that could put her out of a job, writing to a mysterious pen pal quickly becomes her only relief from a life that’s coming apart like a badly bound book.

Peter Montgomery, Duke of Strafford, has spent years trying to get his estate out of debt. Now he finally has the solution in a machine set to revolutionize the publishing industry. If only finding a wife was as straightforward. Peter wants a lady who cares about him, not his title. Someone like his charming, witty pen pal—the only person in London who knows his most intimate secrets but not his real name. But when Peter’s invention makes them bitter rivals in person, can the bond they’ve created on paper survive the test?
