An Affair with Mr. Kennedy (Gentlemen of Scotland Yard) by Jillian Stone is $1.99.
This is a Simon and Schuster book so this is really is a good deal. She's a new author to me. This seems to be book one of a new series. Book two is due out in September. FictionDB labels this as a Victorian Romance.
I just love the cover on this book! Have you ever bought a book because you just fell in love with cover?
I have and it turned out to be one of my favorite books.
Edit: Just read this won a Golden Heart Award in 2010 for Best Romantic Suspense. Original title? The Yard Man.
