"Artificial Condition (The Murderbot Diaries, 2)" by Martha Wells
https://www.amazon.com/Artificial-Condition-Murderbot-Martha-Wells/dp/1250186927/

Book number two of a seven book series of science fiction novellas and
novels. I reread the well printed and well bound hardcover novella
published by Tor in 2018 that I bought new from Amazon. The first
novella in the series, "All Systems Red", won the 2018 Hugo, Nebula,
Alex, and Locus awards. The series won the 2021 Hugo for Best Series. I
have all six books in the series and have ordered the seventh book which
is to be released in November 2023.

Murderbot is a SecUnit, similar to a T-800 Terminator with a cloned and
severely modified human head. There is a human brain in there but it is
controlled by the AIs embedded in its genderless torso. There are
lungs, there is a blood mixture with a synthetic, there is human skin
over the entire body, there is a face, there is hair on the head and
eyebrows. Everything else is machine. Somehow, the blood is enriched
with electricity as there is no stomach or intestines. But, there are
arteries and veins to keep the skin and brain alive. All of the major
arteries and veins have clamps to stop bleeding in case of damage. There
is a MedSystem computer with an AI, a HubUnit computer with an AI, and a
governor module that can force the SecUnit to follow orders using pain
sensors in the brain. It has a energy gun in each arm and several
cameras, all directly wired to the brain. The SecUnit can sustain
severe damage to everything but the head and still survive.

Murderbot is a self named SecUnit due to an unfortunate circumstance
with 57 miners on a remote moon. It has hacked its governor and no
longer allows the governor to give it orders or inflict pain. It
prefers to internally watch its 35,000 hours of downloaded media such as
episodes of "The Rise and Fall of Sanctuary Moon" and "WorldHoppers".
Even though it has a face, it does not like to interface with humans,
yes, very introverted. It will follow human orders if it sees fit to do so.

Murderbot is on the run from its new owner and has been called a rogue
SecUnit by the news feeds. It has been hitching rides with AI Bot Cargo
and Transport spaceships by sharing it's 35,000 hours of downloaded
media. It hitched a ride with an AI ship carrying cargo named ART that
had an incredibly powerful AI. At first, the AI was hostile and then
turned into a friend, helping Murderbot to disguise itself by modifying
its body structure and helped Murderbot take a dangerous security job at
the moon where it reputedly killed 57 miners.

Quotes from the book:
1. “Sometimes people do things to you that you can’t do anything about.
You just have to survive it and go on.”
2. "So they made us smarter. The anxiety and depression were side effects."

Warning: There is violence and death in the books. Books one through
four are a series of novellas, not regular length books. Book five is a
regular length novel, book six is back to the novella, and book seven is
a full length novel due out in November 2023. You can buy a collection
of the first four hardbacks at a nice discount.
