The politics and the dream-like (though not truly Kafkaesque) narrative of Kavan's Ice

Anna Kavan, from the brief intro note in the 50th-anniversay edition of her (last?) novel, Ice (1967), appears to have been a writer (British?) who suffered from a number of mental illnesses and other troubles and used these struggles, or managed them?, by incorporating dream-like and paranoid episodes into her narratives. Ice, judging from the first 50 or so pp., is an unusual work in many aspects: It's a story of a man who returns to an unnamed country (presumably England) from some kind of traumatic event (possibly WWII?), to help the country in some unspecified way through an approaching crisis. His mission, which at this point anyway is completely vague and unclear, gets sidetracked as he goes to visit a woman whom he used to be in love w/ (she's now married to someone else). On his visit he gets lost and waylaid on dark country roads and then has visions of massive forms of ice filling the landscape, and of the woman he's to visit as encased and angelic in block of ice. The narrative proceed apace as he follows someone he thinks is this woman into a northern country (probably Norway?) where much lies in ruin (as much of Norway did after the war). He visits the head of the government to get a permit to stay and study the history of the region; the leader lives in a remote castle, and the narrator's visit to him will call to mind in most readers the dark, scary absurdities of Kafka; Kavan is not as dark nor as "political"; her writing is more surreal and dreamlike, with quick shifts of scene and atmosphere and elements of the supernatural. She is, however, prescient in her politics, as much of what she's writing about is today known as climate change: She envisioned an ice age (with the odd explanation that the planet would cool as the polar caps melted because less heat would be reflected from the polar ice - a theory anyway).
