| "There's no point in beating around
the bush: this book is a masterpiece. Stylistically what makes
it especially good is its restraint; it has none of the loony
excess of late-period Dick, but all the inventiveness and vision
of his best work is here, carefully modulated and controlled.
Nothing in the novel is superfluous, everything contributes
to theme and form -- because this book is very much more than
a straightforward SF narrative. It is a meditation on the nature
of history, a quasi-philosophical work cast in fictional form,
as are several of Dick's masterpieces from his great Decade
(1962-72, or thereabouts). "
