Have you read Ancillary Justice by Ann Leckie? Its the first in a trilogy. If you like good characterization and worldbuilding I highly recommend. I'm always on the lookout for good books, and I'll check a few of these out.
I've heard of Ted Chang, but never bothered to read anything by him.
As a side note, I'm glad to see that this kind of post is doing relatively well on Steemit.
keep it up!
