All Systems Red (The Murderbot Diaries 1) by Martha Wells

“SecUnit, aka Murderbot, is a semiorganic corporate profit center, genderless and constructed of cheap parts to perform contract bodyguard services for clients who mostly don’t want them. SecUnit can choose its attitude because it has hacked its governor (a hat-tip to Susan R. Matthews), blocking the functions that would punish it for anything but robotic obedience. Disgusted by humans and secretly addicted to a video serial called Sanctuary Moon, SecUnit is simply enduring another assignment until something completely outside of its data parameters tries to kill its humans. Nebula finalist Wells (Edge of Worlds) gives depth to a rousing but basically familiar action plot by turning it into the vehicle by which SecUnit engages with its own rigorously denied humanity. The creepy panopticon of SecUnit’s multiple interfaces allows a hybrid first-person/omniscient perspective that contextualizes its experience without ever giving center stage to the humans.” — Publishers Weekly, Starred Review
