From the back of the book:
Paranoids. Sociopaths. Pyros. Kleptos. Delusionals. They're all here -- and you're one of them. Enter the world of Asylum, where the United States has been reduced to a collection of walled Wards, built from former cities and surrounded by desolate wastelands. The sun has been gone for over a hundred years, hidden from view by the airborne algae called Blanket Seed, and everyone has gone mad. Those in the Wards are called Inmates, and they are cared for by Staff and watched over by the Orderlies who are as insane as they are.
Fight for your survival in the violence-prone streets or up on the Beltway. Ponder who you really are, and attempt to discover if any of the equally tenuous people nearby can be trusted. Try to eke out a living with your Occupation, selling your wares or your services in the bazaar-like Mall. But, most of all, whether you revel in it or despise it, accept that the world is no longer sane, no longer ordered, no longer normal.
