A life and death struggle between four women on an advance construction team on Callisto. They are paving the way for a human settlement out of the reach of the all-encompassing AI that controls Earth.
However, they are not as far out of reach as they think they are, as they find when the robotic mech equipment turn on them, and it’s a question of whether they can overpower the mech, and reboot them to factory settings, before the mechs do for them.
The story is set up quickly and the combat is fast-paced, held back by the odd paragraph explaining the technology, one element of which is crucial in determining the outcome.
Not a particularly strong story.
