As was suggested below (by Koland and Bookratt, if my memory serves me right), I am starting a thread just for romances offered for free or at bargain price during Read an Ebook Week.
Smashwords have more than 2000 pages (that's more than 20 000 books) on offer. I won't even try to slog through everything, but here are some titles that caught my eye.
Elizabeth Ashtree,
Maiden's Mistake (REW25 for 26% off). Although I've never read an historical by her, I love her contemporary romances, so I'll definitely be getting this one.
Marguerite Butler,
Compromising Prudence (26 % off), a regency romance which seems to be self-published or indie-published, but has an ornithologist hero.
Jenna Petersen has published several books with Avon. She offers the regency novella
Undeniable, the short story anthology
Almost a Spinster and the novel
The Secrets of a Lady for free, and the regency novels
The Temptation of a Gentleman,
The Desires of a Countess (check it out, it has a remarkably silly cover picture) and
Rogue for a Night at 50%.
Wendy Soliman, who has published historical romances with Robert Hale and Carina Press, offers two of her Hale books at 26% reductions:
Lady Hartley's Inheritance and
Duty's Destiny.
Brenda Hiatt is also a veteran Avon author. She offers
Scandalous Virtue (75% off).
Virginia Henley has written a number of historical for Signet. Her
A Rough Wooing (free) is set at the Scottish-English border at the time of James I. The story
Letter of Love (free) is an Elizabethan romance, and
Wild Hearts is another Scotland-set historical.
Mary Lancaster's
A World to Win (26% off) is set in Hungary during the 1848 revolution, which deserves a mention even though the book is probably self-published.
Mary Gillgannon's
Dragon of the Island series (4 volumes) is available at 50% off. These are Dark Ages historical romances with some fantasy elements and were first published in 1990s, with at least one volume at Zebra in the early 2000s. Alternatively, you can buy the series as single titles:
