Imperial Auditor Miles encounters a dangerous conspiracy on Komarr. He also finds it necessary to control a growing and inappropriate attraction for a lovely lady he meets.
Also, this being a Lois McMaster Bujold story, there are mysteries to unravel and good bits of action/suspense. Good book.

For some reason I absolutely loved this one. New setting, new characters, perfectly introduced. Human drama felt so true. I'd reread it in a heartbeat.
