I was all excited when I ran across this book in the clearance section of Barnes and Noble:
I'm not a big fan of Charity Girl, but I like Lady of Quality, and the cover design is pretty. Plus, the book is in hardcover, something Heyer's various publishers haven't offered since, like, the 1970s. I've been buying the lovely Sourcebooks editions of Heyer's books, but I wouldn't mind picking up a couple of these hardcover editions, too, particularly if the two-books-in-one combo was a pair I loved (the more Heyer the merrier, as far as I'm concerned).
Sadly, when I got home I discovered that this seems to be the only Heyer book Sterling Publishing is offering, and I'm betting it was published specifically for Barnes and Noble's sale section. So if you'd like to own (non-large-print) hardcover editions of Georgette Heyer's books, hitting eBay for the E.P. Dutton versions is still probably your best bet.
