It had been some time, since I'd read the first two books of this trilogy. Probably, because I couldn't find this volume at my local library. I ended up buying it for my Nook, and I'm glad I did. I'm a sucker for space opera, and this series has a lot of the elements that make this genre great. There's political tension, between two governing bodies of human territories, a superior alien race with secrets, a kick-ass protagonist, with a secret of her own, and a hidden artificial intelligence, created by the heroine's partner & shipmate. Oh, and a group of isolationist terrorists, and a long-dead other alien race, to boot. Mix all these elements together, and you have a fun, exciting trilogy, that you'll probably read fairly quickly.
