This book starts with young Miles Vorkosigan doing 17-year-old shenanigans in space. It's super fun, fast paced with the most absurd heist escapades. I couldn't help but love Mile's "in control" attitude but also internally panicking about the situations he put himself into. 
The story includes a lot of military strategy, which is never boring due to its absurdity.  Miles is an engaging character—confident, super smart, and likely has ADHD (super active). We also see him struggling with his decisions and feeling uncertain, making him relatable despite his crazy choices.   He's lucky and always wants to help people, so it's hard not to like him. 
 Miles has a physical disability and knows his limitations (most of the time), but he never feels like less of a person because of it. Overall, he's a very confident and funny guy. It was a fun read. 
I want to continue with the series.
