In the afterword to Cordelia's Honor, this statement is made: "Shards/Barrayar, as it finally evolved, became a book about the price of becoming a parent, particularly but not exclusively a mother. Not just Aral and Cordelia, but all the other supporting couples took up and played their symphonic variations on the theme, exploring its complexities: Kou and Drou, Padma and Alys, Piotr and his dead wife, Vordarian and Serg and Kareen, and most strangely and SFnally, Bothari and the uterine replicator." ―Lois McMaster Bujold
