This is a compilation of two novels, “The Warrior’s Apprentice” and “The Vor Game” and a novella, “The Mountains of Mourning”. The collection introduces Miles Vorkosigan, a young man whose body is malformed and fragile, but whose brains and talent (along with some luck) make him admiral of a fleet of space-going mercenaries. It’s good space opera with interesting characters and a well-developed backstory. In fact, there are times when the backstory is more interesting than the plot, which can be frustrating for the reader but gives Bujold’s creation a unusual degree of depth.
