It was definitely a bit of a slower read (the book was more than halfway through before the plot really started), but I do very much like Breq as a protagonist and I'm interested in seeing where the rest of the series goes, especially now that the next book (presumably) won't be half flashback. 

Leckie has a lot of fun, novel ideas about these almost hive-mind soldiers and what happens when part of the hive breaks off, and I like seeing the examination of the brutal, space imperial society that Leckie developed.
