November's One Dollar Book from Orbit is Blood Ties, by Pamela Freeman, the first in her Castings Trilogy (Deep Water and Full Circle are $9.99 each currently in the Kindle store).
Book Description
A thousand years ago, the Eleven Domains were invaded and the original inhabitants forced on the road as Travelers, belonging nowhere, welcomed by no-one.
Now the Domains are governed with an iron fist by the Warlords, but there are wilder elements to the landscape which cannot be controlled and which may prove their undoing. Some are spirits of place, of water and air and fire and earth. Some are greater than these. And some are human.
Bramble: a village girl, whom no-one living can tame ... forced to flee from her home for a crime she did not commit.
Ash: apprentice to a safeguarder, forced to kill for an employer he cannot escape.
Saker: an enchanter, who will not rest until the land is returned to his people.
As their three stories unfold, along with the stories of those whose lives they touch, it becomes clear that they are bound together in ways that not even a stonecaster could foresee - bound by their past, their future, and their blood.
Not every ebookstore has been matching Orbit's suggested sales price on their dollar books, but I'll include links for the major ones here, so you can check for other formats besides the Kindle one above. Currently, none of the links have updated with the new price, so be sure to check closely before ordering.
