Clans Of The Alphane Moon by Philip K. Dick

On a remote moon settled by former psychiatric patients, society has splintered into rival clans organized around different mental conditions, each fulfilling a civic role. When a bitterly divorced intelligence operative and his psychiatrist ex become entangled with a push to reassert Earth’s control, political scheming, assassination plots, and culture clash threaten the colony’s fragile equilibrium. The turmoil probes the line between sanity and madness while questioning whether an unconventional society deserves the right to govern itself.
