Bikerscum - Patrick St. Jean

I finished reading The Course of Empire tonight. It's a collaboration between Eric Flint and K. D. Wentworth, two authors whose solo projects I have enjoyed immensely.

Humanity has been conquered by the Jao, but the conquest hasn't gone all that well, and the Jao's enemies are on the way to wipe out humanity in an ancient war. It's a very well written book, with believable characterizations, good plots, and pretty much everything else I've come to enjoy from both of those authors.
