This is one of the best books I've read this year. Eric Flint has created a consistent, believable premise, and follows it to a great conclusion.
The Jao have conquered earth and been in control for 20 years now. There is great concern the evil Ekart will be coming to eradicate life on earth soon, but the people on earth are not cooperating with the Jao to build the forces necessary to fight the onslaught. Resistance movements still exist in many pockets of the planet, and the Jao governor is becomingly increasingly brutal and disturbed.
A young Jao from the prominent clan group is newly assigned as the number 3 leader on earth. His clan is noted for deeper thought than the clan of the current governor, and he for the first time begins to bond with a few earth people. He takes some into his personnel service, and begins to maneuver to oust the current governor.
Flint creates the Jao completely unlike us in motivation and response, and does an excellent job creating the Ekart as well. This book completely captured my attention with a combination of philosophy, politics, and warfare. It will satisfy any fan of Drake, Weber, or C.S. Forrester with his thoughtful mix of character and action.
Please Mr. Flint, bring on the sequel!
