Captain Vorpatril's Alliance

I quite enjoyed Captain Vorpatril's Alliance, the 15th book in Bujold's long running Vorkosigan saga. Can you successfully mix humor, intrigue, and romance in a science-fiction tale? Well you can if your name is Lois McMaster Bujold.
The main characters are happily unmarried Captain Ivan Vorpatril and a refugee from Jackson's Whole called Tej. The story begins with Ivan temporarily on Komarr, assigned as aide-de-camp to Admiral Desplaines. His plans are interrupted when Imperial Security agent Byerly Vorrutyer shows up at his flat late one night and asks him to help out with Byerly's current investigation. Ivan has misgivings, but reluctantly agrees to help. Byerly stresses that all he needs to do is get find out what he can about an attractive young woman who might be in danger. (Obviously he knows Ivan's hot buttons.)
From that point, nothing goes as Ivan expected. He soon finds himself sheltering two young women on the run, dodging kidnappers, and caught up in the intersecting machinations of Jackson's Whole plotters and ImpSec. His life will be forever changed.
Good book.
