Miles Vorkosigan is a military cadet about to be stationed to his first assignment. His father is a famous general and has a long list of accomplishments. Miles isn't so lucky; at first look, he is seen as a failure by his peers due to the physical abnormality he was born with. He must work harder, think harder, and be better to get the recognition he feels he deserves.
The world in The Vor Game (1990) by Lois McMaster Bujold is an expansive one with a rich history and backstory around it. Miles is very sarcastic but endearing in what he wants and expects from others. If you are looking for a great series that has an interesting main character and world, then this is a good option to explore.
