All Systems Red by Martha Wells,

 All Systems Red by Martha Wells, 171 pages

A SecUnit which calls itself Murderbot has hacked its command module; now instead of a mindless drone, a budding personality is emerging. Desperate to keep itself separate from the humans it has been hired to protect, Murderbot learns of an unforeseen plot against the team. 

All Systems Red is my first foray into the Martha Wells catalog. I cannot wait to dive in further. The characters were compelling, the writing kinetic, and the worldbuilding was solid.
