I have the five books which constitute Roberta Gellis' Heiress series.  Although many of her books are set in 13th century, these are during the Regency period, but more concerned with continental Europe going from the beginning of the French Revolution into the Napoleanic Wars and the last book is in the period before his first exile.  I would prefer that these go as a group since if you like one you will probably enjoy them all.  Warning might not be for the faint of heart or weak of stomach.  Gellis does not shy away from some pretty grim stuff, especially in the first book which covers the beginning of the
Revolution and the Reign of Terror.  These books don't appear to have been reprinted since the original issue in the 1980s.  Three of the books are adequate but worn.  One had a broken spine which I have attempted to tape together.  And one had lost the front cover - my dog does not always appreciate the time I spend reading, or maybe she wants to see what is so interesting.  Body of the books all complete.  The English Heiress, The Cornish Heiress (no front cover), The Kent Heiress, Fortune's Bride (broken spine) and A Woman's Estate (quite worn) 

I am also offering The Dangerous Baron Leigh by Emily Hendrickson, also with damaged cover

Beckett's Last Stand by Kasey Michaels, some cover loss

The Female Eunich by Germaine Greer, also without a cover but this time it was not MY dog's fault
