I just bought Blood’s Force by The Daily WTF contributor Ellis Morning, because the blurb had a kind of Connecticut Yankee in King Arthur’s Court vibe to it.
More details on Google+. Or just buy it on Amazon for six bucks.
Here’s Ellis’ announcement post on Ghost Town.
Or you can (and should) preview the book here. Blood’s Force is an excellent little sci-fi tale with capable protagonists and constant tension throughout. My only disappointment was that Ms. Morning ended the story where she did; I want moar.
