The wormhole plot was very interesting and satisfying, as was the full worldbuilding of Komarr itself, but what really shone brightest in the novel was Miles's falling in love with a married woman. I knew from a previous readings how important she'd become, but my goodness this was painful to watch. Delightful, absolutely, but also very painful. It was strangely believable and full of depth and realism, greatly surpassing all of his other love interests, and it really brought out the shine in his eyes. Ill-fated love story, anyone? At least the plot actions were entirely believable and felt very natural. Their mutual discovery was slow and the tension was great, and by the end of the novel, still up in the air. As it should be. 
 To say this was a great Miles story is to say it is absolutely required reading. Like most of them. Go get them. Now. Love them. :)
