Several hundred years after nuclear war, Davy begins to write the story of his life.
After accidentally killing one of the guards in the village compound in which he grew up, Davy flees, narrowly avoiding getting involved in a territorial war, and joins up with various travellers - including a mutant, a man who claims to be his father, a travelling carnivale and finally some seafaring wanderers with whom he finally settles on an island in the Azores.
Initially illiterate, Davy is taught to read and write by an old lady in the travelling circus, and thus defies the controlling Church's prohibition on reading texts from before the Apocalypse.
In some ways this is a nostalgic look at an America in pioneering times, since society has regressed to that level, and confines itself to an area between Philadelphia and the Catskill mountains. The leader of the group that Davy joins makes some of his living by selling a universal Panacea, 'Mother Spinkton's Home Remedy', which is claimed to cure more or less everything.
The Church is portrayed as a restrictive and anachronistic force and there are signs that its power and influence are in decline.
Although not as powerful and original as 'A Mirror For Observers' this is a thoughtful and idiosyncratic work, very redolent of Simak in its yearning for a pastoral America, but at the same time critical of religious political control.
Overall it is a compelling portrait of a teenager's passage into adulthood and his changing attitude as he learns and experiences conceptual breakthroughs.
It is to be noted that the human mutations in this work are simply that. Refreshingly the 'Mues' that are encountered show no signs of fantastic powers but are merely severely brain-damaged and/or physically deformed.
It is perhaps too romantic a vision of a post-nuclear world, but then, the novel is not about that. It is about characters and their lives, all of which are beautifully portrayed.
