The Drowned World

Numerous later paperbacks exist (later Berkley Medallion numbers such as F1266 in 1966, plus Penguin and others) — do not confuse them with F655. A Science Fiction Book Club hardcover also occurs: identify it by the absence of a price at the jacket flap, a blind-stamp or blind dot to the rear board, and thinner boards/cheaper paper; it is not the Gollancz first.
