"When Murderbot's human associates (not friends, never friends) are captured and another not-friend from its past requires urgent assistance, Murderbot must choose between inertia and drastic action"--

"Everyone's favorite lethal SecUnit is back in the next installment in Martha Wells's New York Times bestselling Murderbot Diaries series. Am I making it worse? I think I'm making it worse. Following the events in Network Effect, the Barish-Estranza corporation has sent rescue ships to a newly-colonized planet in peril, as well as additional SecUnits. But if there's an ethical corporation out there, Murderbot has yet to find it, and if Barish-Estranza can't have the planet, they're sure as hell not leaving without something. If that something just happens to be an entire colony of humans, well, a free workforce is a decent runner-up prize. But there's something wrong with Murderbot; it isn't running within normal operational parameters. ART's crew and the humans from Preservation are doing everything they can to protect the colonists, but with Barish-Estranza's SecUnit-heavy persuasion teams, they're going to have to hope Murderbot figures out what's wrong with itself, and fast! Yeah, this plan is... not going to work. The Murderbot Diaries All Systems Red Artificial Condition Rogue Protocol Exit Strategy Network Effect Fugitive Telemetry System Collapse"--

It has a dark past - one in which a number of humans were killed. A past that caused it to christen itself Murderbot. But it has only vague memories of the massacre that spawned that title, and it wants to know more. Teaming up with a research transport vessal named ART (you don't want to know what the A stands for), Murderbot heads to the mining facility where it went rogue. What it discovers will forever change the way it thinks...

A murderous android discovers itself in "All Systems Red", a tense science fiction adventure by Martha Wells that interrogates the roots of consciousness through Artificial intelligence. In a corporate-dominated spacefaring future, planetary missions must be approved and supplied by the Company. Exploratory teams are accompanied by Company-supplied security androids, for their own safety. But in a society where contracts are awarded to the lowest bidder, safety isn't a primary concern. On a distant planet, a team of scientists are conducting surface tests, shadowed by their Company-supplied 'droid -- a self-aware SecUnit that has hacked its own governor module, and refers to itself (though never out loud) as "Murderbot." Scornful of humans, all it really wants is to be left alone long enough to figure out who it is. But when a neighboring mission goes dark, it's up to the scientists and their Murderbot to get to the truth.
