After a nuclear war in 1998, 21st century Scotland is one of the few places in the world where human beings still exist. (Tasmania is another, apparently.) In this society it has become customary for people walking outdoors to wear radiation suits, not to protect them from fallout (the suits are ineffective for this purpose), but to hide whatever deformities they may have. The number of birth defects is high, as is the suicide rate. Like most stories set after the holocaust, life is not as enjoyable as it used to be.
