In this haunting and surreal novel, the narrator and a man known as 'the warden' search for an elusive girl in a frozen, seemingly post-nuclear, apocalyptic landscape. The country has been invaded and is being governed by a secret organisation. There is destruction everywhere; great walls of ice overrun the world. Together with the narrator, the reader is swept into a hallucinatory quest for this strange and fragile creature with albino hair. Acclaimed by Brian Aldiss on its publication in 1967 as the best science fiction book of the year, this extraordinary and innovative novel has subsequently been recognised as a major work of literature in its own right.
