I'll third
A Year in Provence. An excellent book, and I'd love an excuse to re-read it.
I'll also second
Downbelow Station. I'm sure I read this when it first released, but I'm always game for an excuse to read Cherryh. And here's some links to the book:
Kindle (US) edition.
Audible
Amazon CA (Way overpriced. buy it at the US store.)
Amazon UK
Kobo Canada (seriously overpriced)
B&N (Also way over priced)
