Cordelia's Honor

Shards of Honor - Betan Cmdr Cordelia Naismith and enemy Barrayaran Aral Vorkosigan are attacked and marooned together. Aral, misnamed "Butcher of Komarr", captures her. They exchange meanings of honor and love, separate for homes. Later demoted to Captain, Cordelia runs into Aral, after his sadistic cousin Vorrutyer, and warped ugly bodyguard Sgt Bothari. Cordelia flees Betans who ignore truth.
Barrayar Aral is appointed Regent of baby heir by dying Emperor. Cordelia, now pregnant Lady Vorkosigan, breathes antidote to poisonous gas. Her son Miles has fragile bones that break on birth and will limit his adult height and durability.
