The adventures of Murderbot continue in novellas three and four from New York Times bestselling and award-winning author Martha Wells, collected in paperback for the first time!"Who knew being a heartless killing machine would present so many moral dilemmas?" Science fiction's favorite antisocial A.I. is back in Rogue Protocol! The case against the too-big-to-fail GrayCris Corporation is floundering, and more importantly, authorities are beginning to ask more questions about where Dr. Mensah's SecUnit is. And Murderbot would rather those questions went away. For good. In Exit Strategy, Murderbot is heading home to help Dr. Mensah--its former owner (protector? friend?)--submit evidence that could prevent GrayCris from destroying more colonists in its never-ending quest for profit. But who's going to believe a SecUnit gone rogue? And what will become of it when it's caught?
