A few more recommendations:

This is a sweet romance that takes place in New York after World War I. Nice characterizations and some really snappy dialog. I'd give it 4 out of 5 stars.
I think this book has been mentioned before...a cowboy romance with a twist:

It's a very sweet story. It's aimed at the young adult market so not as sophisticated as some of the stuff I read, but I enjoyed it nonetheless.
I finally finished:

Historical fiction, set in France in 1815. Great descriptions and a good mystery, with lots of twists and turns.
