"Ice" is the main novel by British writer Anna Kavan, who was compared to Virginia Woolf during her lifetime and called Kafka's sister. Critics consider Kavan a pioneer of the slipstream genre—a literature of imaginative fantasy where cause-and-effect relationships hang by a thread, and heightened emotions are incomparably more important than logic.

In her novels, realistic depictions suddenly ripple, and unexpected images and scenes emerge from the depths of the subconscious.
