Borders of Infinity (Vorkosigan Saga [Publication] #5.1-5.3)

The popular adventures of Miles Vorkosigan, a clever and outlandish science fiction hero for the modern era, continue in these three tales. In The Mountains of Mourning, Miles is dispatched to a back-country region of Barrayar, where he must act as detective, judge, and executioner in a controversial murder case.

In Labyrinth, Miles adopts his alternate persona as Dendarii Mercenary Admiral Naismith for an undercover mission to rescue an important research geneticist from Jackson’s Whole. And in the title story, Miles infiltrates an escape-proof Cetagandan POW camp and plays hero to the most deeply distressed damsel of his colorful career.
