Winterbirth by Brian Ruckley
Synopsis
An uneasy truce exists between the thanes of the True Bloods.
Now, as another winter approaches, the armies of the Black Road march south, from their exile beyond the Vale of Stones. For some, war will bring a swift and violent death. Others will not hear the clash of swords or see the corpses strewn over the fields. They instead will see an opportunity to advance their own ambitions. But all, soon, will fall under the shadow that is descending.
For, while the storm of battle rages, one man is following a path that will awaken a terrible power in him -- and his legacy will be written in blood.
So far, the pricing has come down at Booksonboard (Adobe Digital Edition only) and Sony. It should drop soon also at Fictionwise (ereader) and Amazon. Amazon has been the latest with this promotion every month, so far. They've already announced the bargain pricing on their deals page, but the listing itself hasn't caught up, so just keep checking it.
Update: Amazon now has this listed at $1, so one-click away.
