Cordelia's Honor by Lois McMaster Bujold

Captain Cordelia Naismith is forced into a temporary truce with her captor and chief opponent, Lord Aral Vorkosigan. When Vorkosigan is betrayed by his men, Naismith considers her options, and decides to join with him for survival. This book is a combination of two earlier books, Shards of Honor and Barrayar, forming a continuous story of the two lives destined to be together through the birth of their son, Miles. A good read.
