Vorkosigan saga

When his boyhood chum, Gregor, the Imperial Emperor, goes awol, chance places the exiled ensign Miles Vorkosigan in a position to extricate Gregor, the Dendarii Mercenaries, and himself from a very sticky and potentially deadly political situation

A rich Komarran merchant fleet has been impounded at Graf Station, in distant Quaddiespace, after a bloody incident on the station docks involving a security officer from the convoy's Barrayaran military escort. Lord Miles Vorkosigan of Barrayar and his wife, Lady Ekaterin, have other things on their minds, such as getting home in time to attend the long-awaited births of their first children.

When a Kibou-daini cryocorp--an immortal company whose job it is to shepherd its all-too-mortal frozen patrons into an unknown future--attempts to expand its franchise into the Barrayaran Empire, Emperor Gregor dispatches his top troubleshooter Miles Vorkosigan to check it out.

"Three years after her famous husband's death, Cordelia Vorkosigan, Vicereine of Sergyar, stands ready to spin her life in a new direction. Oliver Jole, Admiral, Sergyar Fleet, finds himself caught up in her web of plans in ways he'd never imagined. Meanwhile, Miles Vorkosigan, one of Emperor Gregor's key investigators, this time dispatches himself on a mission, into a mystery he never anticipated--his own mother. Plans, wills, and expectations collide...

Being a Vor lord on the war-torn planet Barrayar isn't easy, but Miles Vorkosigan has natural leadership qualities. Perhaps that explains how he managed to forge a secret identity and became the leader of a force of spaceborne mercenaries even after being washed out of the Barrayaran Military Academy.

Still new to her duties as Lady Vorkosigan, Ekaterin is working together with expatriate scientist Enrique Borgos on a radical scheme to recover the lands of the Vashnoi exclusion zone, lingering radioactive legacy of the Cetagandan invasion of the planet Barrayar. When Enrique’s experimental bioengineered creatures go missing, the pair discover that the zone still conceals deadly old secrets.
