IT ISN'T EASY, BEING VOR...

Being a Vor lord on the war-torn planet Barrayar wasn't easy. Being an officer in Barrayar's military wasn't easy. And being the leader of a force of spaceborne mercenaries while maintaining a secret identity wasn't easy—in fact it should have been impossible, to say nothing of being a capital offense on Barrayar. Not that impossibility or great danger would slow down young Miles Vorkosigan much.

The Warrior's Apprentice 1
Discharged from the Barrarayan academy after flunking the physical, a discouraged Miles (17) takes possession of a jumpship and becomes the leader of a mercenary force that expands to a fleet of treasonous proportions.

The Mountains of Mourning 373
Miles (20) is sent to a small mountain village to investigate the murder of an infant, killed because she had a physical defect. Miles must deal with deep-seated prejudice against “mutants” and uncover the real killer in this novella that won both the Hugo Award and Nebula Award.

The Vor Game 465
Miles (20s) faces enormous challenges in this Hugo Award-winning novel as he leads a mutiny against his military commander's criminal orders, rejoins his Dendarii mercenaries, and attempts to rescue Emperor Gregor after Barrayar's royal scion has run off straight into trouble.
