Was I in a mood that I didn't enjoy Revenant Gun or has something changed in Yoon Ha Lee's writing? I can blame it partially on the fact that I didn't remember anything from the previous books, but I do remember I enjoyed them!
Reading my review of the previous book I see some similarities in feeling: I don't remember much of the story or characters from before and it feels a bit sluggish at the beginning and rushed at the end. But the difference is that I had trouble finishing Revenant Gun and, instead of fondly remembering the situation where the other two books left off and getting closure, I felt like I had difficulty empathizing with any of the characters or caring about the story.
And it's not like it's a straightforward book. It has two different threads, in one there is a resurrected Jedao reluctantly serving Kujen, the other is another Jedao, inhabiting the body of Cheris. Then there are a zillion officers, hexarhs, servitors, moths, lots of gay love that is unrelated to the story, but may have a place in the culture of this military universe and so on. The writing was decent, but it didn't blow me away.
Bottom line: Perhaps the lucky ones are those who will read the entire trilogy at once and get both the freshness of the concepts and the closure of the story in one go. As such, I got almost nothing from this.
