I thought this book was pretty good, though it has a bit of a rough start. Once you get past the initial part and get used to the first/second person narrative it becomes much better. It's also not a particular long story, but the characters, especially the Strength and Patience of the Hill, are cool.
I can recommend this as a quick jump into Ann Leckie's works, particularly if you are more interested in fantasy than her usual science fiction.
