Re: What Fantasy/Sci-Fi book have you just finished? Please rate it...
The Last Colony, by John Scalzi. Sequel to Old Man's War and The Ghost Brigades, and including the major characters of both.
Well written, and well thought out. The Colonial Union Government, previously working as a functional if somewhat cold-blooded organization, here shows the drawbacks of being unrepresentative and responsible to no one, and the main characters have to tread a thin line between surviving and being traitors...
I'd give it a 4 out of 5.
