As always, books on my watch list pop up on sale when least expected. As of today's alerts:
The Invisible Woman - 2.99 (recently made into a movie, thus the new cover)
America's Women - 1.99
Out of Africa and Shadows on the Grass - 2.99
Which means that if you like perusing Amazon for sales it might be worth it to take a peek and see if there's anything else interesting on sale.
In particular there's a whole page of Loved the Movie? Read the Book with all ebooks on sale for 2.99 or less.
