Miles Vorkosigan failed his physical test in a military academy - he has a lot of birth defects. He also happens to be a son and grandson of great military leaders, he is expected to excel in military field, and his expulsion from the academy is a huge disappointment for everybody, first of all: his grandfather. Miles decided to take a break and visit his mother's home-planet. Before he knows it, he is an owner of an obsolete spaceship and an imaginary mercenary company.
One of the best space opera I read lately. It has everything: action, betrayals, romance, more actions, and - most important part - character development. This is book #3 in Vorkosigan saga, but it can be read as a standalone. It was my first exposure to Ms. Bujold, definitely not the last. Highly recommended for any SF fans, 4 solid stars.
