The bastard legion
(Book)

Four hundred years in the future, the most dangerous criminals are kept in suspended animation aboard prison ships and "rehabilitated" in a shared virtual reality environment. But Miska Corbin, a thief and hacker with a background in black ops, has stolen one of these ships, the Hangman's Daughter, and made it her own. Controlled by explosive collars and trained in virtual reality by the electronic ghost of a dead marine sergeant, the thieves, gangsters, murderers, and worse are transformed into Miska's own private indentured army: the Bastard Legion. Are the mercenaries just for fun and profit, or does Miska have a hidden purpose connected to her covert past? -- from Amazon.
