So for November, it looks like Carina Press is having two separate sale offerings when you buy their DRM-free ePubs direct from them:
1) For $1.99, you can
pre-order White Dawn, the 1st book of Susan Edwards' previously published "White Dawn" western-looking historical romance series of 12 books, which will be regularly priced at $4.99 each. The first four volumes are slated to be e-released on Nov 21st.
Description
Missouri River, 1810
Broken-hearted and abandoned in the wilds of America's untamed West, sixteen-year-old Emily Ambrose is rescued from certain death by solitary trapper John Cartier. Though she's learned the hard way not to trust any man, she can't help but feel safe with the kind stranger.
John can't imagine anyone willingly letting Emily go. Her strength and beauty call to him, but it is clear her wounded heart needs time to heal, and he won't settle for just her body. He vows to return Emily to civilization—and to resist the desire growing between them, unless she turns to him out of love.
Emily is drawn to her rugged but gentle rescuer, and begins to feel the passion that a woman can feel for a man. But she can't embrace a future with John as long as she's haunted by secrets of the past...
2) Also for $1.99, you can have your pick of 15 specially selected novellas (normal retail $2.99, typical Amazon discount to $2.51 for the one I test-searched) throughout the end of November.
They're all listed on this page here, and no coupon is necessary for either these or the above novel offer.
