I picked this up on the basis of an unusual and interesting premise but until near the end I didn't know what to make of it. Full of Ballard's verbose and symbolic imagery, this story explores some very adult themes and is not for the easily offended. As the protagonist increasingly believes that the "sins of this world are metaphors for virtues in the next", he proceeds to break down taboos in the town of Shepperton as the reader is left to ponder the meaning of this idea.
As we follow Blake's transformation into some kind of messianic figure, biblical metaphors abound and the town of Shepperton becomes a kind of garden of Eden until realisation of his and humanity's ultimate destiny finally dawns on him.
My high rating of this book reflects more my intellectual appreciation of what the author was trying to do more than my emotional response and personal enjoyment which otherwise would have led me to rate this book lower. Take from that what you will.
