In the rigid prison-world of the Jug, Captain Liam O'Leary believes order, rehabilitation, and class duty can hold society together—until he meets Sue-Ann Bradley, a detainee who refuses to accept the role assigned to her. Her case, tied to the forbidden crime of violating the Categoried Class laws, exposes a civilization built on genetic specialization, inherited status, and the dangerous idea that people must never mix across boundaries. O'Leary's confidence begins to crack as he sees that the prison's hierarchy may be less natural, and far more fragile, than he has been taught. Sent to the brutal Greensleeves disciplinary block, Sue-Ann is overwhelmed by green straitjackets, tangler fields, and the deranged cries of hardened inmates Sauer and Flock, prison "wolves" who seem to have become one with confinement itself. When Flock turns his apparent agony into a hidden escape attempt, the prison erupts into chaos, and the takeover spreads beyond the walls into the city-state. As alarms sound and military forces mobilize at Hap Arnold Field, the crisis reveals how quickly a society obsessed with control can be shaken by the very people it tries to classify and contain.
