These are the continuation of a series I started last month. They were pretty good. Evidently some of the short stories and other novels in this series have won the Hugo. I don't know that they were that good, but I enjoyed them.
The main character of these books is the son of the main characters in the first two books. His parents are attacked by poison gas while his mother is pregnant with him and as a result he is born with stunted, brittle bones. due to wars of the past, His society is paranoid to the point of superstition about "mutants" so he has an extra hard time.
All this serves as background for some very well plotted stories. The ones dealing with Miles Vorkosigan feel like running downhill, one thing leading to another in a very wild sequence. Very enjoyable space/military sci-fi, doesn't take itself too seriously.
