This novel was chronologically the last one in the Vorkosiverse for several years until Cryoburn came out. Miles and Ekaterin are diverted from their honeymoon as Miles is ordered to Quaddiespace in order to sort out a diplomatic tangle involving an interned Komarran/Barrayaran trade fleet. Needless to say, complications abound as a Cetagandan plot involving haut unborn babies is uncovered.
Not knowing at the time about Cryoburn coming years later, it was quite bittersweet to read the last of the books. While Diplomatic Immunity is not the best of the Vorkosigan books, it certainly does not disappoint. As usual, the enormously talented McMaster Bujold demonstrates her prowess at seeing things from many points of view. Her descriptions of Quaddies, their actions and thought patters, are particularly impressive. A lot of thought was obviously given to how even basic mannerisms could be decidedly different for humans with four arms, no legs, and a life in zero gravity habitats. The interaction between a happily married Miles and Ekaterin is charming and alluring, leaving the reader hungering for many more books. Perhaps it is a good thing that the author quit when at the top of her game, but I couldn’t help feeling at the time that Miles, and now Ekaterin, still have many stories left to be told.
This novel is collected in the “Miles, Mutants and Microbes” omnibus.
