Worth the Risk. Marriage by Obligation Series, #4

He's been a recluse his entire life... All of his life, Mr. Reuben St. George has been sickly. His older brother has done everything he could to keep him safe and healthy, so for all of Reuben's life, he's been forced to stay in the country. When he's allowed to go to London to attend a Season, he finds the perfect lady to marry: Miss Amelia Carnel. And has been forced back to his country estate... London is a big place with a lot of people, and all it does is make him sick.
As a result, he's unable to attend quite a few social activities. The most frustrating part is that Amelia has other suitors. Healthy suitors who can give her a normal life. As much as he hates to admit it, his brother is right. He needs to return to the country and let Amelia stay in London so she can marry someone who can give her the kind of life she deserves. But he never bothered to ask Amelia what she wants, and she isn't going to let him get away so easily. *This is a steamy regency romance that features a virgin hero and a virgin heroine.
