Plot summary
Miles and Ekaterin Vorkosigan are enjoying a delayed honeymoon off-world while their first two children are approaching birth in their uterine replicators back on Barrayar. On their way home, Miles receives Emperor Gregor Vorbarra's command to go to Graf Station in Quaddiespace to untangle a diplomatic incident in his capacity as the nearest Imperial Auditor. There, he is unexpectedly reunited with the Betan hermaphrodite Bel Thorne, a trusted former Dendarii Mercenaries subordinate and his good friend.
Quaddies are the result of genetic manipulation centuries before (as described in Bujold's novel Falling Free). Intended to be used as laborers in zero-G, they have extra arms instead of legs. However, the invention of artificial gravity rendered them useless to the corporation that created them. They stole a spaceship to avoid being liquidated and colonized a remote star system. At Graf Station, the Quaddies occupy a zero-G section, while visitors use a section with artificial gravity. Quaddies tend to be suspicious of other humans based on their history of callous exploitation.
A convoy of Komarran merchant ships are being prevented from leaving the station due to trouble caused by Barrayaran personnel from their military escort. Furthermore, a Barrayaran security officer is missing, possibly murdered or deserted.
