The Cog: Prison 17 Re-Education Centre

From publisher blurb:

Location: Harmony on the moon Opal.

Overview

Prison 17 or the Cog is one of the largest and most feared detection centres in the city of Harmony on the oppressive moon of Opal. Known as a Re-education centre, the Cog holds political dissidents, activists and others that the ruling council would like silenced but which prove too useful to ‘remove.’ Instead, these prisoners are kept at the whim of the State with no trial or hope of release, doing as asked by their captors on pain of execution. Prison 17 is notable for the number of scientists, intellectuals and political activists held within its walls.
